Hi, everyone i have little problem.I host few sites but thoes site witch are in wordpress like this
http://www.salespc.net/ load very slowly.
I enable varnish and mod_speed and still have slow speed, in gtmetrix before i enable mod_speed and varnish they has more bad score, but no still sites work very slowly.After enable varnish sometimes shows:
error 503 backend fetch failed.
CWP is on VM with I3-3*** 12GB RAM, 1 Gbit network.
Can you give me some advice for speeding up sites?
