Confusing HDD Performance Issue of Plesk, Important!

[OytunO]

Hello,

My server is running so slow when all plesk services are up, I tested HDD with HD Tune Pro utility, i got 0.7 mb/s - 1.2 mb/s read scores.

I have 8 gb ram on win 2003 enterprise edition 32 bit, my max. ram usage is 1.80 - 1.90 gigs for 200 domains. cpu usage is %5 max.

Server's cpu and memory usage is not high, there arent any high usages on them, just seems hdd is overusing somehow.

When I close plesk and all its services, I got ~90 mb/s read scores with hdtune pro, and server runs faster as expected.

Time and usage not matters, if i start plesk, hdd goes so so so slow, reads at 1mb/s.. even there is no traffic usage for domains at late hours..

Why can it be happening? Which points or logs do i need to check to resolve or find out this situation?

Thanks

Is anyone facing the same issue?

Strange issue... I never heard about it. I think that it should be investigated by experienced supporters directly on your server. Therefore contact support team if you can't find a reason by yourself.
