Finally i decided to request Server optimization.
according to this
this thread i got all the information but i mm stuck on step no 11. "if you run Apache and you have your own dedicated server or access to your httpd.conf (apache configuration file) can you post the values you have set for the following :
KeepAlive
MaxKeepAliveRequests
KeepAliveTimeout
MinSpareServers
MaxSpareServers
StartServers
MaxClients
AND Maxrequestsperchild value ="
Could u please tell me how to do that i will be thankful to you
