envonge Posted April 22, 2009 Share Posted April 22, 2009 Your cpu usage is basically 100% idle how is that a lot of usage? Link to comment Share on other sites More sharing options...

Grey F0x Posted April 23, 2009 Share Posted April 23, 2009 :blink: :blush: oups sorry i thought that it was 99% usage. an other stupid question in the system overview i can not see the ram usage Current Server Load 0.00 Total Server Memory MB Available Physical Memory MB do you know why? thank you Link to comment Share on other sites More sharing options...
rct2·com Posted April 23, 2009 Share Posted April 23, 2009 No. But from your original post:Mem: 563200k total, 136420k used, 426780k free, 0k buffers Swap: 0k total, 0k used, 0k free, 0k cached That suggests that your server is either very, very lightly loaded, or you have a sub-optimal Apache and MySQL configuration. MySQL would LOVE to cache a lot of your tables in memory if you let it. :) You also have NO disk allocated as meory cache [Swap: 0k total]. That isn't very clever either.

Grey F0x Posted April 23, 2009 Share Posted April 23, 2009 thank you but how can i change all this settings? and make the best performance? thank you Link to comment Share on other sites More sharing options...
rct2·com Posted April 24, 2009 Share Posted April 24, 2009 As I understand it, the 'swap' size is decided when the operating system is installed. I don't know how to change it post-installation, sorry. As for MySQL tuning, there are no hard and fast rules. It all depends on actual database usage. I have found www.mysqltuner.com useful, but it needs lots of iterations and gradual changes over time. Link to comment Share on other sites More sharing options...
