loading speed of webpage slowed down after https enabled, how to improve?

I ran that script twice, the first time was interrupted by remote server:

and the second time running was halted at the last line:

It seems that this script can not help me to find the bottle neck.

Then I ran "top" command, the result shows that "clamd" was using 99% CPU! Though this number alters frequently, but always very high:



Does this means that I need to do some work on ClamAV software?

Thank you.

There is links to topics and some temporary solution

Which nginx template are you using? Domain > edit

cache
hosting
default

hile.

[baijianpeng]

I will try to check and change the group and owner of that directory. I know nearly nothing about Linux, so I need to copy some command and paste into my Xshell window.

My nginx template is: Default.

[baijianpeng]

I found that command but the command can not find that directory, there is no such a directory named "clamav", so strange!

Code: Select all

[root@localhost ~]# chown clam.clam /var/run/clamav
chown: cannot access ‘/var/run/clamav’: No such file or directory
[root@localhost ~]# 

[baijianpeng]

Ok, I created that directory manually and changed the group/owner and then restarted clamd:

Code: Select all

# mkdir clamav
# chown clam.clam /var/run/clamav
# systemctl restart clamd

Now I check with "top" command, the "clamd" is not even in the list! I watched the list refreshed for almost 30 seconds, the highest number of CPU load is 10% .

It seems that the CPU occupation by ClamAV problem solved?

But the webpage loading speed seems not improved.

I just wanted to add that I also had this issue (unrelated to https) but with ClamAV eating all the CPU.

In my case the directory was there, it just was not owned by the proper group/user.

Immediately after running the below command the issue was resolved:

Code: Select all

chown clam:mail /var/run/clamav/

I'm running CentOS 7 and a fresh install of VestaCP

Thanks, man.
We have this bug - https://bugs.vestacp.com/issues/122
Something changed in clamav, I'm sure, we'll fix this.

[baijianpeng]

Today I noticed a weird thing: the /var/run/clamav directory on my CentOS 7 was disappear and my CPU usage roar up to 99% !

Then I had to manually create (mkdir) that folder again and assign owner and group to it again.

But, the point is: Why this folder was completely gone? Someone had attacked my server and deleted it ? I have no idea.
