  • OK, so here is my server config. information.

    1. Is this a dedicated or shared server?
    Dedicated
    2. Server Specs
    Single processor Pentium 4, 1.6Ghz generic. 512MB of 266 DDR
    80 GB EIDE HDD
    Apache/1.3.26 (Unix) mod_gzip/1.3.19.1a PHP/4.3.6
    Linux 7.3
    3. innodb?
    I don't think I'm running any of these tables.
    4. Mysql was installed via RPM

    5. Top Stats:
    1:50pm up 15:05, 1 user, load average: 0.66, 0.57, 0.83

    The server is nowhere as busy right now as it would be at night.

    8. VB is not the only thing on the server. I actually have three sites running vb on this machine. 2 of them are VB3, and have almost no traffic. This site running 2.3.3 is by far the busiest site I have on here. I'm also running phpadsnew on two of the sites, including the busy one.

    9. My cookie timeout is 5400 seconds, and I average 375. I've had a max of 862. Usually in a 15 minute period, I have about 150 users online.

    10. http://www.dieseltruckresource.com/dev/admin/extras/phpinfo.php

    11. Apache Variables:
    Keepalive = on
    MaxKeepAliveRequests 1000000
    KeepAliveTimeout 120
    MinSpareServers 10
    MaxSpareServers 50
    StartServers 50

    12. VB Version 2.3.3

    I hope this helps.


  • With that many users online you may want to consider going to 1 Gb RAM. :)


  • Wow, over 650 users online and no issues. This was the fix I needed! Thank you so much for the help. It all worked like a charm! Turck is a beautiful product, too :)
    Good to hear :) Remember after server upgrade to come back for a tune up :D


  • More details about my issue can be found in this thread:


    http://www.vbulletin.com/forum/showthread.php?t=119221


  • Wow, what a difference! The mmcache has dropped my server load a good 50% at least. So far so good. Thanks for the info ! :)


  • More slow queries. This is getting ridiculous. The only thing I can think of is a corrupt database based on the fact that it worked fine until a week or two ago.

    yup turck mmcache has been known to do just that :D


  • Wow, over 650 users online and no issues. This was the fix I needed! Thank you so much for the help. It all worked like a charm! Turck is a beautiful product, too :)


  • Thank you. I'll let you know how it goes. :) I appreciate it!


  • Your phpinfo link gives a forbidden error

    Sorry, I'll turn it back on.


  • I'm planning on doing some upgrades. I'm thinking a dual proc Dell 2850 with 2GB RAM would do the trick. This machine needs to go but these changes have made a HUGE difference. My server load has been under 1.00 all evening. Now THAT is awesome. :D


  • Hi, Steve asked me to post this, but I never got a response, and I'm still having problems. I've not gotton any more responses in my original thread either. Could you guys take a look and let me know what you think? I would appreciate it.
    sorry about that seems your thread slipped through some how :o

    As to your problems I'd do the following first in this exact order

    1. upgrade MySQL to 4.0.20 or 4.0.22 (skip 4.0.21)
    2. upgrade PHP from 4.3.6 to 4.3.9
    3. change /etc/my.cnf to below and restart mysql server




    [mysqld]
    port = 3306
    socket = /tmp/mysql.sock
    log-slow-queries
    skip-locking
    datadir=/var/lib/mysql
    skip-innodb
    max_connections = 650
    key_buffer = 16M
    myisam_sort_buffer_size = 64M
    join_buffer_size = 1M
    read_buffer_size = 1M
    sort_buffer_size = 2M
    table_cache = 1024
    thread_cache_size = 64
    wait_timeout = 3600
    connect_timeout = 10
    tmp_table_size = 32M
    bulk_insert_buffer_size = 8M
    max_allowed_packet = 16M
    max_connect_errors = 10
    query_cache_limit = 1M
    query_cache_size = 16M
    query_cache_type = 1

    [mysqld_safe]
    open_files_limit = 8192

    [mysqldump]
    quick
    max_allowed_packet = 16M

    [myisamchk]
    key_buffer = 64M
    sort_buffer = 64M
    read_buffer = 16M
    write_buffer = 16M


    4. install Turck Mmcache http://www.vbulletin.com/forum/showthread.php?t=75878

    5. Upgrade to Apache 1.3.31 - you didn't provide the maxclients value in httpd.conf ? can you provide it ?

    After all is done test above for 1-7 days to see how it goes, then

    6. upgrade to vB 2.3.5 or 3.0.3


  • Your phpinfo link gives a forbidden error
