Load high..
| Posted by howsthat, 11-28-2007, 12:02 AM |
| i was previously using maxclients 256 in httpd.conf and the load was normal even when the server was processing 256 requests..
recently i had changed it to 320 coz of which my load had increased a lot.. Now when i have decreased it back to 256 the load is still high even when the no of requests are just 150..
WHat can be the possible reason

| Also watch the apache status page when the server load goes high to see if any specific site is taking more resource on server. Use the following command from shell to see the database activity.
mysqladmin -i3 processlist

| mysqladmin proc stat
would give you a list of queries including the slow queries

| did you try to optimize your mysql yet? and which script is using python there?

| Posted by activelobby4u, 11-28-2007, 10:18 PM |
| 11638 mysql 15 0 141m 45m 3604 S 190 3.1 15939:39 mysqld
----------
Mysql usage is on top. Its best to optimize it and then proceed
