apache is faster ?

[roomp3]

Hello

i am using lsws for about 3 months , and it was good
one of my server in the last three days start to be very slow
i mean loading web pgaes started to be very slow
the server load is
0.54 (8 cpus)
Memory usage
10 %

when i switch to apache the pages start to load just fine
but when i get back to lsws the page takes about 20 - 30 seconds to load

i have not changed anything in the server
and i dont know from where this issue came

i tried re-installing lsws again and builded matching php binary
but that didnt help


i am using lsws as cpanel plug-in , if this helps


anyone can help me befor get back to Apache + MPM Worker ?

need more detail info to identify the problem. for example disk usage, is /tmp nearly full? any error message in error.log and stderr.log? etc

root@de [/tmp/ubru]# df -h

/usr/tmpDSK           485M   24M  437M   6% /tmp

error.log file are 0 bytes in lsws

looks like lsphp5 crash is the reason of slowness?

you may need rebuild php.

please check /opt/curlssl/lib/libcurl.so.4 is 32-bit or 64-bit. not sure if it's a problem to mix 32-bit and 64-bit library together.

also for:

/usr/tmpDSK           485M   24M  437M   6% /tmp

we have experienced some people use NFS as /tmp, and made lsws very slow. As a quick check, just "ls -R /tmp" to see if it's normal.

root@de [/usr/local/lsws/admin/logs]# ls -al

this is lsws web admin console log, should check /usr/local/lsws/logs

If you use PHP suEXEC, you may need to increase "PHP suEXEC Max Conn" http://www.litespeedtech.com/docs/webserver/config/general/#phpSuExecMaxConn

login to LiteSpeed web console, and check the realtime status page, see if WaitQ is not zero for any external application.
