    Exclamation Server Performance

    Hello,

    Do you see any performance problems for this site?

    Recently, i noticed that, sometimes, the server can not respond on time (rarely it takes many seconds (10+) to return a response). Interestingly, even in those situations, when i check the server with "top" command, it shows up to %50 cpu usage.

    This might be a problem with my connection. I would like to know your experiences.

    Please read: I am making this thread sticky. please post your "server performance" problems and feedbacks here. If you have problems other than "server performance", you can post them to the forum. This thread is for only performance problems.

    I am bad in english and you might find it hard to understand, I just want to share what I am experiencing.

    Mostly I experience delay of showing reply on threads, I was able to tell it because before I post my reply I always
    try to refresh the page so I can see if there were already same reply. Then after I post my reply, and sometimes after 2 to 3 times of refresh,
    I notice that there were earlier reply for about 1 to 3 mins.

    The first few days after the switch I experienced very slow load times on my phone and laptop, but as of late the speed has been perfectly fine.

    You don't ned to care about this. I am in the same situation.

    Then after I post my reply, and sometimes after 2 to 3 times of refresh,
    I notice that there were earlier reply for about 1 to 3 mins.
    Hmm, this is an interesting problem. I will search for this.

    Do you have any speed problems? Do you observer slowness in peak times (e.g. afternoon)?

    Thanks sunde887. Is the site have a mobile web page? :) Or are you connecting to the regular web site? It should be difficult to follow the regular site from the phone.
    By the way, i would like to give you a good news. There will be free android and iphone applications for java-forums in 1-2 months ;)

    Didn't you observe any peek times in which the forum does not respond in less than 10 seconds (since you have registered)?

    Sometimes the response after a submit of a reply is very slow; the impatient little puppy that I am, I try to re-submit (thinking I must've missed the button the first time) and the final result is that I've submitted two or three (identical) replies ... I saw Darryl Burke's duplicate replies as well, so I'm not alone in this ;-)

    kind regards,

    Jos

    I get the regular site through safari on my phone, other than the first few days I've had good performance at all times of the day.

    I'm glad to hear about the app and can't wait until it's released.

    The over-all performance is fine (or at least as before), but there have been times the last week that I could't log in or even could't load a page when I was browsing the site (I have seen "panic-screens" pop up that the site was unreachable but that the operators were aware of the problem and working hard to fix it). Most of the time this situation didn't last long (after 10 minutes or so after a coffeebreak it was OK again).
    No bug ever had to calculate its fitnessfunction.

    I encounter problem in 'Submit Message' button when I am trying to send private message. The said button
    seems not responding. When I check Sent Items it says that I have zero message in sent items.

    Problems for posting to threads and private messages should have been solved now.
    I am making this thread sticky. You can post your "server performance" feedback here. For other forum problems please use this forum, but not this thread please.
    Thanks for the feedback.

    Today approving threads that were marked 'moderated' was very slow. I don't know whether or not it was a problem of a busy network or a server problem. Overall the old forum software seemed faster ...

    kind regards,

    Today, i was trying something related to performance. It slowed down the server considerably and i switched it off. You might see the slowness due to it. May be we should wait a little bit (before changing anything significant) to see how is the performance.

    I guess the server slows down when there are many writes to the mysql. At the end, i might consider buying a raid-based neighbor server and move mysql there.

    If there are people experienced on optimization and performance evaluation of servers, who wants to help, let me know.

    Personally I don't think much of MySQL; do you have an option of switching database systems or is the forum software glued to MySQL?

    It is glued to vbulletin and mysql.
    Here is the excerpt from vbulletin: "Scalable Solution - database server and web servers can reside on separate machines." I guess "purchasing a database server" is the way to make the forum scalable.

    So the vbulletin system is a three tier architecture; that's fine, but why would it be glued to MySQL (the third tier)? For fun: have a look at InterSystem's 'Caché' database system. They also have a free version (which I use occasionally). It can be amazingly fast. Or if you want to do it big, use IBM´s DB2 system. I even think that the 'Mimer' database (produced by a Swedish company if I'm not mistaken) is much faster than MySQL.

    kind regards,

    Jos

    Thanks Jos. I would prefer Java and object databases too but it is hard to find powerful forum software for these technologies.

    I have a new theory for rare performance problems: Searching feature
    Following page describes this scalability problem.

    Sphinx Search for vBulletin 4

    Here is a quote:

    Why Replace vBulletin's Database Search?
    If you are asking that question, chances are you don't need to. If the search system built into vBulletin 4 works well for you, keep using it. Generally, it's something that a forum owner should start thinking about ~500,000 posts, and arguably around 1,000,000 posts it becomes a necessity. vBulletin's default database search is based on MySQL FULLTEXT search. MySQL FULLTEXT search works, but it's not designed to scale well.
    I think i will install vBulletin 4 Sphinx Search when i have time.

    I am impressed with the results. :) No one having problems?
    I am sending a reboot request to the server host at least once a week..
