    Well,

    Actually the content of the site has not improved, because it hardly can become better ;-)
    But when I take a closer look to the current amount of users, the speed has increased :)

    I'd vote for both 'has improved' and 'hasn't changed appreciably'. Right now there are 42 users logged in. I just tried loading this page here several times and found that sometimes the page loads in less than 2 seconds, while at other times it takes about 7 seconds. SO it depends on how many users at hitting the site at the exact millisecond you send your request :)

    I'm sad to have to say so, but the site's responsiveness has not improved at all for me, even though it hasn't worsened, either. It still takes between 5 to 10 seconds for any given node to load, and given that the packet roundtrip time between me and perlmonks.org is only about 115 ms on average, it does not seem to be a network problem.

    But well, good things are worth waiting for, aren't they? ;)

    To my gentle opinion, the performance has improved

    Aren't there some benchmark test on a regular bases so that one can provide real numbers?
    Like with apache's ab command?

    I would say it feels a notch faster. There've been a couple pageloads that came up very quickly - faster than I've ever noticed before. The worst case has not improved though, and average loadtime has hardly improved appreciably. I'm certainly not complaining.

    I don't know, it might be me but I'm thinking the site is a wee bit faster. At the moment I see the majority seem to think otherwise but the nodes I've visited this morning seem to have an extra spring in their step :-)

    Well.... I can't really make out any difference
    There are too many parameters involved
    Like my net connection, number of users on my LAN
    the new server load, etc....
    And i generally have a slow connection speed,
    as i'm in India

    Although the site is still fairly slow, I'm no longer getting "Inactivity Timeout" messages when traffic is high. Kudos to the gods for the fix!

    So why is it that the site takes so long to load? The Chatterbox?
      I guess it's just me, but it's taking longer to load up now. Might be the chatterbox and such, but it loaded faster before.

    Well, the numbers of page erros down. But I think that we need to improve more! I don't know if the site already use some kind of FastCGI or mod_perl, but I know that it can be more fast!

    For example, if Chatterbox make SQL querys for each page, this can be improved using a persistent script (on FastCGI or mod_perl), where the Chatterbox results varialbe will be updated only if the query to the SQL is older than 15s, since this is the time to your msg goes to the site, the other user reload it, read, send the feedback, and you reload! But we stay during this 15s reloading all the time the page! ;-)

    Or the Chatterbox can be in one iframe or other window. I don't know if some browsers will work with that, but we can get the $ENV{HTTP_USER_AGENT} and work around this.

    I think that if some changes to make the users reload less the site, will improve a lot the site! Is like paste a tree through the door of your house. You can change the size or shape of the tree, or of the door, or make the both!

    I don't disapprove of market research, surveying what users thing of the site's performance. However, I think that this is not as useful as an objective benchmark. A big drawback is that people's expectations are variable and inconsistent. Do you expect people to remember accurately how the performance was before the upgrade?

    It is also important to distinguish the different scenarios: "Perlmonks is generally slow", "Perlmonks is appallingly slow today" "Function X (e.g. logging in) is slow".

    Presumably, with a minimum impact to performance, the Everything code could cut a log entry of its own when the page completes, giving the request type, start and finish times for each HTTP request. At the end of the day, a script can munge the log files and produce statistics about response times.

    I presume that the bottleneck is in MySQL database access. In that case, turning on Devel::DProf for some sample periods could provide useful insights, without making the site unusable.

    Also, Pair can presumably provide statistics on busyness, in terms of hit rates and number of accesses per interval. This would give an objective measure of whether the site is generally being used more heavily.

    I've voted 'improved', as I think its a bit faster overall in fetching nodes etc.
    The problem seems to be at peak times, (thats evening here, mornings are lovely and fast :), when about 50+ users are on (according to the CB/full page chat), then I get timeouts again. Though as its usually about the time I go to bed, I'm not complaining. :)

    Maybe this has been addressed before, but it seems to me the CB would be the biggest drag on site performance. To use CB, you have to constantly refresh the screen but making yet another web page request. I'd be willing to bet that if CB was off, general site performance would improve radically (not that I'm suggesting removing CB).

    Moving on to the "not this again" section. Is there a way to make CB refresh automatically (using perl, not Java)? If that was the case, then there would be far fewer page requests, as people wouldn't bounce around just to refresh CB.

      Yes there is. Just use full page chat if you want to participate in the CB for a longer amount of time. It refreshes itself, and doesn't need to reload any of the sections to do it.

      C.

      Another big drag is the Other Users nodelet. If at all acceptable, you should turn it off.

    Could be purely coincidental, but I've found the site to be much slower since the past couple of weeks. It takes about 90 seconds for each page to load. But then again I am on 36.6k dialup. I rang the local telephone exchange and had the line gain of my phone line increased, to no avail. Guess I'll just have to bear with it. Seeing as other websites like Livejournal also seem to be slow then I guess it's not a PM problem.

      And I'm on a T1 and it seems to take 2 minutes. Go figure.

      Site was really sloooooooow last week. Seems to be performing nicely today. What OS did they upgrade to? Was it a new OS or just a new version?

        What OS did they upgrade to?

        Windows XP

        Just kidding, FreeBSD I believe :)

    After hours of consideration I have reached the following conclusion: It has gotten considerably faster, however I realized it doesn't really help. Not when your internet connection is as slow as mine!

    yea gotta agree.. I can't really tell since my isp is so unreliable, but in overall I think the site's speed is pretty good.
Response Time Tracking

    I have begun sampling site responsiveness on an hourly basis. A graph depicting the results for the preceding seven days can be seen on my home node: Dr. Mu. This graph will be updated once each day after midnight, Pacific Time.

    is there some node with more info on this "upgrade"?
    i'm just interested in all the backstage stuff going on here...
    for me perlmonks was never really slow - but maybe it's my 56k connection...
