one website loads very fast other very slow

[hamdiboy]

Hello,

I use i use same script on different domains.

One of website loads very slow ( 40 secs) other websites loads in 1 sec .


So i think that there is some limits.


what should i do ?

[hamdiboy]

i have one cpu license


root@server [~]# netstat -an | grep 80 | grep ESTA | wc
1120 6720 99680

and some times all websites loads very slow

Ext App WaitQ piling up (781, 446, etc) indicates your "PHP suEXEC Max Conn" (http://www.litespeedtech.com/docs/we...pSuExecMaxConn) is not high enough to handle incoming PHP requests. increase to 50 (from 6) and see if alleviate the issue. But this should only affect the sites with non-zero WaitQ.

When all sites load slowly, check realtime stats and see if more sites have non-zero WaitQ. also run 'top -c' from command line and see other processes consume cpu cycles.

this is my new real stats,

we are still having some problem

top -c did not help me to see anything intresting :/

looks like having been improved by looking at the graph.
one busy site still have the problem(WaitQ=498).

try to enable anti-ddos feature, see if can resolve the issue.
especially
Server --> Security --> Per Client Throttling --> Dynamic Requests/second, tune it to 5,10,... to see if any difference.

it did not helped.

how can i run php in different mode is there any way to work without externall app ?

[webizen]

That vhost (with WaitQ=498) isn't busy. However, it takes a long time (somewhere ~20-30 seconds) to complete the php request (even the incoming is only 5 requests/sec). Hence WaitQ pile up. You need to check the script and see why it takes long time to complete. Thing like the script pull resource from external site, etc.

the intresting thing is

i am using same db and script on different two websites.

one of them loads very fast ( over half second) other one loads in 30 secs.

it is the same DB and same script.

there is a limit based on vhost i beleive.

how can i raise it?

wrong assumption.
you can compare the configuration between the website.
and adjust any limit to have the bad one match the good one.
