Library Performance

Recommended Posts

For the last four or five days we have received a number complaints, both in email and posted on our forums and newsgroups, about the slow down in the library and the frequent "server too busy" notifications. I would like to show you some information that clearly shows the issue.The first image is that of the number of downloads over the last 7 days. This was recorded at 0400 on Wednesday, March 8th.

As you can see, the file library suddenly leaps from an approximate average of 70,000+ downloads a day to over 192,000 on the 4th of March. Guess what happened on that day? The posting of the Canaray scenery package.Now let me show you another image of the bandwidth consumed...

Same deal. We are averaging 500+ megabytes of bandwidth a day until the 4th of March. Suddenly we jump to over 3 TERABYTES. In the three days from the 4th through the 6th, the library served up a total of over 7 TERABYTES of files to the 450,000+ members of our library system. TERABYTES... I encourage everyone to go out a get a quote for what 7 terabytes of bandwidth costs. You will be shocked. And that is for just 3 days.It is disheartening to get complaints and to realize that there is an apparent total lack of understanding from some in the simming community about the very infrequent periods when a "we're too busy" response results from a download request, or that the download speed has dropped to "just" 20 KB/Sec from the normal "xxx,000" KB/Sec.Those that complain should understand that on an average day our library's performance is outstanding, especially in light of the fact that access is given evenly to all downloaders, and for FREE. We don't charge for premium / 1st class / preferred / whatever, access. But I can tell you that after this episode I am beginning to think we have two alternatives: disallow any file that WE anticipate will be popular for fear of what it may do to performance so we don't have to listen to the abuse, or to do as others have done... Charge for preferential treatment and limit bandwidth for all those that don't pay to some miserly amount and with limited download time over a 24 hour period...I don't think people appreciate what they have in AVSIM, and I am getting very tired of the attitudes of some. I will leave it at that.

Well said, Tom. I agree 100%; now and whatever AVSim decides to do in the future. Sorry for the abuse you've suffered; patience seems to be sorely lacking when it's needed most.Bob

Agreed.My only comment is, don't slam the majority for the fact the minority are a pack of ***kers....The majority of people here would not give you this grief, though I fully understand your.....disappointment.I love Avsim! Cuts into "quality time" at night with my partner. Eventually she will realise that Avsim is a 24-hour website, and then I'm in huge trouble ; )CheersTimNZWN

We carry spousal / partner / friend insurance. If you get into really deep kimchee, give us a call. We have a number of lawyers from New Bedford, Mass, who for a case of cheap wine and air fare, will take care of the problem. :)EDIT: Just to respond to the serious part of your message, we do understand that the few who complain are a very small minority of the community. But, having said that, some of the email we get and the forum / newsgroup postings are way over the top and hard to accept. We are, after all, just human too.

Tom, I fully support you guys and understand. It amazes me to see so many negative posts when a new developers website exceeds it's bandwidth and then they jump on them and complain, some just have no clue (or life!).Just post the complainers to the general forum and let us have at them, LOL (a dose of their own medicine)Thanks for all you guys do to make this hobby as great as it is.Regards, MichaelKDFWhttp://www.calvirair.com/mcpics/mcdcvabanner.jpgCalVirAir International

I for one am very grateful for everything AVSIM has done for this community and hate to see it dissed. For you sourpusses, Just imagine for a moment if you will, the simming community without AVSIM. Would you prefer to slog your way through a "Allnodesarebusy.com" or some other alternative pay per view service? I think we're all a bit spoiled at times by the services provided here. Best to keep it in perspective and realize the enormous investment in time, energy and resources, financial and otherwise, by so many that have made it what it is today. A slow or throttled download once in awhile and expecting some civility is a very low price to pay.Ok, I'm just rambling now. Keep up the great work Avsim.

I think that patience is one of those elusive qualities that the majority of people seem to adopt late in their lives - if ever. Nowadays everything has to be "Now!", unfortunately. I wonder how many of those who scream murder at the slightest drop in speed of their precious transfers from the library over here ever take the time to actually ENJOY what they download? Or is it just the superficial excitement over a new acquisition which is forgotten the very next day?I agree with others who responded to this post - it's a minority. A vocal one, but still a minority. I'll add my thanks and appreciation for everything that is AVSIM and silently slip away to the treasures of the Library. More to download! Aahhh... ;)Thanks Tom & AVSIM!Regards,Jure

Hi there Tom it's too bad that a small number of people in this world are so selfish (and greedy I might add) I believe that it seems to be a part of daily living in general these days that it's allways good to just sit and cry when one can't get instant anything. That haveing been said please keep in mind that the vast majority DO understand that you might just have to wait for things in life and if a download takes a little longer on some days oh well that's life. I for one NEVER take for granted for the services that you and your staff provide. A greatfull Dan Martin

Hi Tom,Just wanted to say how sattisfied I am for AVSIM's great Free! library service. Usually you get wat you pay for but with AVSIM file library this isnt the case :-)You guys are a cornerstone for the FS community. May I suggest that we refer the few whiners to get their files over at "all nodes are busy.com" ?Enough said.

If they're not happy with the service, they're free to go elsewhere.This can be quite easily achieved by making sure they always get a DNS error trying to reach the site :)

I look on my time at Avsim much the same way I would look at an invitation to a friends house. One does NOT antagonize one's host (at least not if you want to be invited back.) Count me as one of those who are very grateful that Avsim exists. I come here almost every morning for my news and, often enough, downloads. I'd hate to have had to pay for all the stuff I've DLed. :D

I really did not post the above to solicit or grovel for gratitude, though I am sure the staff of AVSIM and certainly I do appreciate your thanks and encouragement.My intent really was to point out that we do provide a pretty good service, all in all, and for free and that albeit a minority, there are folks who take for granted our contribution to the community. When we witness the departure of freeware authors from our hobby, or to commercial endeavors because of the words of a minority, we can certainly relate. We see it every day in our email, pm's, and forums, but addressed to us.I have said this before and I think it needs saying again... AVSIM is the greatest FREEWARE product / service in our community. 24 hours a day, 7 days a week, 365 days a year, and doing that for nearly 10 years... A sustained effort that I don't think anyone can match. I can't think of any other freeware in our community that matches the effort or personal investment of time (read "our lives") than AVSIM. That isn't intended to besmirch or denigrate the efforts of other freeware contributors, but hopefully to put AVSIM and the efforts of all of our volunteers, into perspective.

It *is* a very, gvery good service tha Avsim is providing. And I cannot understand, why there is so much impatience and lack of thankfulness around here.Avsim, along with all those freeware authors, really gives an outstanding contribution to our hobby. Yesterday I searched the web for some simple clipart pictures. I could not believe my eyes when I found almost everything was payware, even some small dotted lines. And then I thought: What am I expecting? Must everybody offer his/her work for free on the net, so that I can have it immediately while forgetting to say thank you?Avsim does so, it offers a huge pool of fs resources for FREE! I can only hope that those who were complaining read this post along with those tables provided by Tom.But in the end, that won't probably change very much, because there will allways be people who didn't learn anthing else but to take everything for granted....I just hope that Avsim will continue to offer superb service under the current conditions. Maybe a heartfelt "thank you" from all of those who don't complain will help :)Greetings from GermanyAlex

Hi Tom,Well here in the UK I got up from my bed at 0545 to download the Canary Scenery - time well spent. I think Avsim has done a fantastic job, as always. Give my congratulations to all concerned.KenSomerset, England

Tom,I still remember when Avsim was struggling and you were ready to pull the plug. Many of us encouraged you to continue with the great Website. I also remember that you banned people from the forums (don't know about the file library) when they did not behave properly in "your housd". You know that I have always, and all ways, appreciated Avsim and will continue to do so. Thanks, again, for the service that you provide to the FlightSim community.

Hi Tom,Pretty Good???? Amazing, I'd say.I, too, want to thank you for all the work you have done and for everything you provide. I totally appreciate what you offer for forum and download service and everything else. And when the downloading is slow, I come back later. No big deal. The fact that you offer so many files 24 hours a day at such fast download speeds is stunning.Are you based in MA, too? I didn't realize that. If not, why choose lawyers from New Bedford? Is there something about them I don't know, and wish I had learned before?Thanks,Thomas[a href=http://www.flyingscool.com/FC_StartJava.html] http://www.flyingscool.com/images/Signature.jpg [/a]I like using VC's :-)

Actually, they are not lawyers. They are a gaggle of fishermen friends of mine who "take care" of issues for me. Fishing out of New Bedford isn't what it used to be and they work cheap... :)I lived and worked in Falmouth and North Falmouth from 1980 to 1987. Once a "capey" always a "capey". :-lol

Is there a way to limit the number of downloads of popular files? Perhaps another site that has limits, and after a period of time as download rate calms down migrate them to the regular library?I realize you know a heck of a lot more about this than I do. I was just wondering what the possibilities are, 'cause I think it is important, and will only get worse, especially as more and more people join the community.I'm imagining community size is growing exponentially, especially now that MS has acknowledged the community exists and is supporting it to a degree. And I expect there will be a huge jump with FSX (though the little boy in me dreams that all issues will be solved and FSX won't need any updating :)).Thomas[a href=http://www.flyingscool.com/FC_StartJava.html] http://www.flyingscool.com/images/Signature.jpg [/a]I like using VC's :-)

If we limit downloads we might as well go "premium, first class, whatever". For us to setup another server won't really address the issue (but would add over $7,000 to our immediate costs). We would still have finite bandwidth - a huge amount to be sure, but finite never the less. The alternative is for us to "up" our bandwidth limit. Unfortunately, doing that is not a simple linear increase in cost... It goes non-linear and very steeply at that. Beyond what we pay now it would impose a CONSIDERABLE cost impact on the users of our system. In short, we go pay-for-access to increase bandwidth, or we stay as we are and ask users to be patient and to understand the situation. After all, an average of 550 or 600 gigabytes a day with peaks to 3+ terabytes a day is nothing to sneeze at. Folks just need to take a deep breath and appreciate what is being served up by AVSIM for free. If their expectations overcome common sense, then the alternatives are not pretty.

Maybe a disclaimer on the File Library main page:"Downloads from the library may at times be slow, this is usually due to a large and popular newly available file. Rest assured, we are aware of the problem and are doing everything we can to improve download performance"You can use that free of charge. My contribution to AVSIM. Although most people do read anything on that page, at least you tried.Thanks, Team AVSIM.Jim
