Everything is working ok but it is sometimes slow. Any help is welcome. Thank you.
1. Is this on dedicated or shared virual server.
Dedicated.
2. Dual Xeon 2.8ghz
2GB ram
74GB SCSI non raid
Red Hat Enterprise Linux ES release 3
Apache v1.3.34
PHP version: php 4.4.2
MySQL version: mysql 4.1.18
3. if you use mysql 4.x instead of mysql 3.23.x, do you have any innodb type databases/tables on your server?
? I have no idea.
4. if possible how mysql was compiled/installed
With WHM/CPANEL
5. your top stats

6. your mysql configuration variables located at /etc/my.cnf
At /etc/my.cnf I only see
[mysqld]
set-variable = max_connections=500

8. is your vB the only thing on the server? or other scripts & sites which utilise php and mysql?
One vb (850,000 posts, 38,000 members) and one photopost (40,000 photos)
9. how many average and max concurrent users on your vB forum ? and what your cookie timeout is ?
Average 350, max. 1,300. Cookie timeout of 1,200 seconds.
10.
11. if you run Apache and you have your own dedicated server or access to your httpd.conf (apache configuration file) can you post the values you have set for the following :
KeepAlive: KeepAlive On
MaxKeepAliveRequests: MaxKeepAliveRequests 100
KeepAliveTimeout: KeepAliveTimeout 15
MinSpareServers: MinSpareServers 5
MaxSpareServers: MaxSpareServers 10
StartServers: StartServers 5
MaxClients: MaxClients 150
AND Maxrequestsperchild value = MaxRequestsPerChild 0
12. what version of vB are you running ?
vb3.5.4
13. check to see if any files i.e. apache log files are hitting 2GB or 4GB max file size limits i.e. see if you have max file size exceeded messages in apache error log
None hits 2GB.
1. Is this on dedicated or shared virual server.
