Why is litespeed admin panel so slow or even timed out?
I have a 2-core litespeed license, mysql is not running on this server.
It just says "Connecting to 'my server ip' in the status bar of the web browser and gives a timed out error. It happens about 50% of the time. My website is also loading very slow, about 5 seconds to load, sometimes up to 20 seconds to load.
The website also communicates with other websites that I own, I often get "can't connect to 'my domain'" errors which is using Perl LWP. I even get timed out errors from IMAP when sending emails via squirrelmail (PHP).
This is a 12 core server so the load should still be fine. But even if the website is loading slow due to high traffic, why is litespeed admin panel loading so slow also?
I didn't find nf_conntrack, I found ip_conntrack. It was set to 65536 and after setting to 131072 I don't have problem loading that now. Does that mean that before I set it higher, a lot of users were getting timed out and cannot connect?
Usually it is syn attacks cause the conntrack table full unless you have a very hot site. In your case, it is likely syn attacks since there aren't that many connections go to lsws. enable syncookies (sysctl parameter) to alleviate it.
