There is anything I can do to reduce this CPU usage?
I made some changes and it's better now.
PHP suEXEC -> Yes
PHP suEXEC Max Conn -> 100
Smart Keep-Alive -> No
Run On Start Up -> suEXEC Daemon
There's anything else I can do to reduce CPU usage?
build one of opcode cache: xcache or Zend opcache, should reduce the load
Is it correct?
I think I got it. Is it right now?
; ini only settings, all the values here is default unless explained
; select low level shm/allocator scheme implemenation
xcache.shm_scheme = "mmap"
; to disable: xcache.size=0
; to enable : xcache.size=64M etc (any size > 0) and your system mmap allows
xcache.size = 64M
; set to cpu count (cat /proc/cpuinfo |grep -c processor)
xcache.count = 2
; just a hash hints, you can always store count(items) > slots
xcache.slots = 8k
; ttl of the cache item, 0=forever
xcache.ttl = 0
; interval of gc scanning expired items, 0=no scan, other values is in seconds
xcache.gc_interval = 0
; same as aboves but for variable cache
xcache.var_size = 0M
xcache.var_count = 1
xcache.var_slots = 8K
; default ttl
xcache.var_ttl = 0
xcache.var_maxttl = 0
xcache.var_gc_interval = 300
xcache.test = Off
; N/A for /dev/zero
xcache.readonly_protection = Off
; for *nix, xcache.mmap_path is a file path, not directory.
; Use something like "/tmp/xcache" if you want to turn on ReadonlyProtection
; 2 group of php won't share the same /tmp/xcache
; leave it blank(disabled) or "/tmp/phpcore/"
; make sure it's writable by php (without checking open_basedir)
xcache.coredump_directory = ""
; per request settings
xcache.cacher = On
xcache.stat = On
xcache.optimizer = On
; per request settings
; enable coverage data collecting for xcache.coveragedump_directory and xcache_$
xcache.coverager = Off
; ini only settings
; make sure it's readable (care open_basedir) by coverage viewer script
; requires xcache.coverager=On
xcache.coveragedump_directory = ""
yes --- the 1st screenshot of phpinfo, shows "Opcode Cache:disabled"
the 2nd screenshot of phpinfo, shows "Opcode Cache:enabled, ..."
does the load of lsphp5 get dropped ?
Yes, it did.
Thanks again NiteWave!
yes, reduced significantly --- this clearly shows the power of opcode cache (plus litespeed's unique suEXEC Daemon mode)
The only thing killing me now is MySQL haha, I will need to optimize the queries direct on the script I think...
Anyway, it's better now!
