    -joerg please provide the following

    1. your server specs, such as mysql and php version
    2. if possible how mysql was compiled/installed
    3. your top stats
    4. your mysql configuration variables located at /etc/my.cnf or c:my.cnf if on Windows server if you don't have that file you need to log into telnet and as root user type

    mysqladmin -u root -p variables

    copy and paste output here

    5. your mysql extended-status output either still telnet as root user type

    mysqladmin -u root -p extended-status

    copy and paste output here

    or preferred is to installed extended-status output script which is located at http://vbulletin.com/forum/showthread.php?threadid=3477

    and post url to that here

    6. oh and is your vB the only thing on the server? or other scripts? sites?

    7. how many average and max concurrent users on your vB forum ?

    8. create a file named phpinfo.php and place this code in it and post the url/link to it from your web site

    phpinfo();
    ?>

    i.e. yourdomain.com/phpinfo.php


  • Well I set up a friends box, similiar setup with rackshack.. he uses it for vhosting, but has a few mysql sites... keep in mind it only has 512 ram so I didn't want to allocate too much memory to mysql.. this is the config I used for mysql and it seems to be running fine. If I gave it any more the system lagged...

    [mysqld]
    datadir=/var/lib/mysql
    socket=/var/lib/mysql/mysql.sock

    skip-locking
    set-variable = max_connections=400
    set-variable = key_buffer=24M
    set-variable = table_cache=1024
    set-variable = sort_buffer=3M
    set-variable = join_buffer=2M
    set-variable = record_buffer=2M
    set-variable = thread_cache=256
    set-variable = thread_concurrency=2
    set-variable = myisam_sort_buffer_size=24M


    [mysql.server]
    user=mysql
    basedir=/var/lib

    [safe_mysqld]
    err-log=/var/log/mysqld.log
    pid-file=/var/run/mysqld/mysqld.pid

    [mysqldump]
    quick
    set-variable = max_allowed_packet=128M

    [mysql]
    no-auto-rehash

    [isamchk]
    set-variable = key_buffer=64M
    set-variable = sort_buffer=64M
    set-variable = read_buffer=2M
    set-variable = write_buffer=2M

    [myisamchk]
    set-variable = key_buffer=64M
    set-variable = sort_buffer=64M
    set-variable = read_buffer=2M
    set-variable = write_buffer=2M
