Multi cache/setup questions
Hi,
I have just setup CloudLinux/LVE along with Litespeed, PHP 5.3.19, eAccelerator, memcache, and LS Cache.
Have a few questions in preparation for growth and in interest of optimization.
1) How do I know when/if I need to upgrade to a 3-4 core license?
2) Is there any issue having all of these caching setups at the same time?
-- Also, any suggested tuning to make them play nicest?
3) Tuning settings - Ive changed/checked these many times and overall they had minimal effect on test load times for a small wordpress site, or for my main application which will be small web pages and light PHP.
I currently have:
Keep-Alive timeout - 5 seconds
Send/receive buffer untouched as pages will mostly be small ones
IO Event Dispatcher - epoll
Max Cached small file size - 4096b
Total Small Cache Size - 128M
Max MMAP File Size - 256K
Total MMAP cache size - 128M
Use sendfile - Yes
Use AIO - Yes (Also tried keep mapped - any preference?)
AIO Block Size - 1M
No inode in etag - Not set
Max URL Length: 2000
Max Request Header Size - 4096
Max Request Body Size - 500M/default
Max Dynamic Response Header Size - 4096
Max Dynamic Response Body Size - 500M
GZIP is yes/Yes,
Dynamic content- level 4
Static content - level 6Max Static file size - 512K
Cache settings:
Max Object Size - 128K
Cache enabled Yes
With Query string - Yes
Private cache Yes
Everything else no
I post my specific settings as the server is to be optimized for small static or small php pages where speed is the primary concern. On an older dual quadcore xeon with 8gb ram, two 15K SAS drives. Would like to place around 500 users per server.
So far my testing has shown that CPU shouldnt be an issue, but memory perhaps will. I just want to check with everyone here to ensure my tuning is in tip top shape and that Im not missing out on anything.
Thank you everyone.
