Page Load is very Slow

[bahram0110]

Hello
I was installed Litespeed on cPanel CloudLinux server

before litespeed installation, apache was installed and there was no problem.
websites was very fast and server load was 1 to 2

Server :
Ram : 32G DDR3
HDD: 2 x SATA enterprise (Hardware Raid) + 1 SSD for mysql
CPU : Xeon E31245 8Core
CloudLinux 6.3
CentOS 64Bit




after installing trial litespeed, websites are very slow, Server load is 1 to 2
CSF sends many alert about suspicious processes :


you can see response time in this image (from host-tracker):


Can anyone help please?

looks normal to me. the only concern is
Cloud Linux: LVE

how about set it to "Disabled" ?
or other option "CageFS" ?

it's reported before if LVE or CaseFS limit set too low, will slow down the web server.

Hello
I was disabled cloudlinux in Litespeed settings and then restart LS
problem persists yet

[NiteWave]

not sure if the network "hiccup" issue --- to test, switch to apache, see if the response become fast at once ? if slow as well, then network's issue. if it becomes fast, can you post the graph(for apache) from host-tracker

also, are all websites slow or only particular website slow ? how about the pure html webiste or php website without mysql ?

Hello
I don't know why! but port speed shifted to 50 Mbit after installing LSWS.
now problem is almost solved.

static contents (php & html, ...) are very fast (less than 1000 ms to transfer)

some dynamic sites are very fast (100 to 1000 ms)
and some is slow (1000 to 8000 ms)

Do you know what should I do?

[NiteWave]

and some is slow (1000 to 8000 ms)

if it's 1st request is slow, 2nd,3rd ... is fast, may due to "database warming up" issue. please refer this post:
