php - Wordpress on IIS: High CPU Usage -



php - Wordpress on IIS: High CPU Usage -

we're using wp 4.0 on iis 7, , experience high cpu usage: regularly spikes 25% single process (php-cgi.exe) in pool (w3wp.exe), summ on 3 or more processes > 60% (as can seen sysinternals process explorer). checked fastcgi active , installed wincache php - helped bit. , deaktivated plug-ins - brought minor improvement.

our system:

3 intel xeon cpu 3.7 ghz 12 gb ram wp 4.0 microsoft iis 7 php version : 5.3.23 / 32bit os memory limit : 128 mb memory usage : 21.65 mb

any ideas can done this? alter settings fastcgi or wincache? need improve hardware?

your's felix

is production server? guess... more info needed pointing resources have. i'll give points start.

seems have plenty of memory , cpu resources. hardware rock solid , don't need improve hardware! but! 1 big problem see os (in opinion). there else going on machine?

are converting photos, doing cpu intensive operations within wp installation? image optimizers? displaying/resizing images? seek disabling of plugins have , caching - plugins or server side. thing seek changing theme 1 of default ones. how many page hits have?

try setting max instances setting, under iis server --> fastcgi settings, 1.

try trace requests causing php-cgi.exe go rogue , pig cpu.

and after recommend running wordpress on linux machine nginx , if possible lighttpd serving static content, if you're not comfortable both seek running apache 2.4 mysql 5.5. install oracle vm virtualbox illustration , run debian os or whatever sense comfortable , see, if have same issue. if windows os not needed else (which don't know yet), if possible switch favorable linux.
