    Hello,

    The last days I visit the forum, I get sometimes very long waiting times (upto 2 min.).
    Sometimes I get a blank screen afther the waiting time.
    Are other members also experiencing the same ?

    Hi bertus,

    Are you talking about page loading times?

    Personally I do not have any page loading problems, I would be interested in hearing if others are having issues.

    Hello,

    It says sometimes a very long time "waiting for www.allaboutcircuits.com" in the status line of the browser.
    Afther the waiting time I get the page or even a blank page.
    It is not always so slow but sometimes as I said.

    For the record could you list up your browser and version. I take it you are having no issues at other sites? Also have you tried clearing cookies for AAC?

    My set up is IE7 and Opera 9.63 on Vista and I am not having issues at this time.

    I would be interested in seeing if others are having issues, and we can investigate further if need be.

    I will have a look at the cookies.

    Ever since I joined I have found substantial speed variations, depending upon the time of day.

    Sometimes pages time out for me instead of loading. And somethimes things can go really smoothly for weeks.

    I find the same effect with other forums, so it is not unique to AAC.

    I log on on the nearest available machine, from Linux through W98 to Vista but mostly the internet dedicated machine is W2000 with IE6. I see no real difference between machines, some wireless some ethernet.

    The DSL is unlimited maximum available and as I watch the activity lights I often see my end of the connection waiting for a reply from the blue yonder out there.

    Hi all,

    I'd certainly like to hear about other folk's loading times for the forum/site. We have had a huge increase in traffic in '09, and I had thought the server was handling it well. If a lot of people are experiencing a slowdown, I will get to tweaking the server settings, add more RAM, etc.

    I generally have superb response time from the AAC server, even though it's across the pond from me.

    Occasionally, I do get time-outs, and have lost more than a few replies. I blame it on the routers in the net; there are generally around 14 hops between myself and the AAC server in a most bizzarre series of loops on this side of the pond. :rolleyes:

    Hello,

    I have even 16 hops if I do a traceroute:

    So, perhaps the router are messing up sometimes as SgtWookie said.

    PS I will try to repeat it when the line is slow.

    Hello,

    I have tried a traceroute during the "long waiting time" and that works normal.
    The server responds also on it.

    Hello,

    I noticed that the "long waiting times" occur more between 10.00 AM and 10.30 AM (GMT +1).
    Has it to do with planned tasks on the server (backups) ?

    Yes a hiatus seems to happen most days (today for instance) at this timeslot. I assume that you are changing over servers around then and just come back later.

    Hello,

    It is not the number of users online.
    It was "only" 300 at that moment.
    I have seen numbers upto almost 700 without problems.

    then it must be server loading problem or system changeover processes during data Xmission. :rolleyes:

    The number of users is about 350, so that is not the problem.

    Mine are 3:00AM to 4:00AM, the board actually dies for a short while (timeout).

    I've always assumed backups.

    Bill you're absolutely right. During that time is when the daily cron jobs are executed, which include database backups, etc. Since these processes utilize much of the server's resources, it causes the site itself to slow down.

    Hello,

    Are the cron jobs executed at the same time ?
    Are there many cron jobs ?
    Can they be spread over the day ?
    Cron jobs can be executed at the time of day you want to spread the load on the machine.
