yes , i have modify the httpsd.conf to reduce the thread from 3 to 2, i will try to let it only maintain 1 thread.
I think vivalite 's turn it off solution is good. since most of time, i don't use Plesk to manage server. i can start the httpsd service only when i need it. then turn it off when i have finished.
turn it off, save 40M memory
I agree. That's an acceptable solution if you do not use Plesk frequently.
