php - Website on IIS server takes 10-15mins to load -


i have big website many visitors daily. when large increase in visitors website keeps loading 10-15 minutes (for long time).

this not dos attack, have figured out. it's iis php, because see many (100+ fastcgi.exe) php fastcgi.exe processes in task manager.

my ram , cpu fine, have 128gb ram. use 8-9 gb ram.

i think website script loading ever , stuck. has iis setting set script running higher? have checked logs , can see this:

the fastcgi process has failed recently

i using windows server 2008, can replicate behaviour on windows server 2012 also. i'm using wincache opcode cache.
