Cyberpanel 65% Ram Usage Enough to handle 150+ concurrent?

iz
izaan #1

i have installed wordpress on cyberpanel and i am expecting 7-8k daily visitors with 150+ concurrent connections and the current ram usage showing in cyberpanel is 68% with 22 concureent so i want to know if this much ram usage is normal? if there are 100+ concurrent then can it handle?

cpu usage spikes to 40-50 then goes back to 10-12
and is there any way to check my memory usage in numbers?
in my vps panel its showing that litespeed is using 371mb

VPS SPECS:
2gb ram
cpu: don’t know how to check that.

Edit: Plugins i have:
Wordfence
Yoast Seo ( Recently installed i think it’s using lots of usage)
Litepseed
Some Theme Plugins
Really Simple SSL
OneSignal Push Notifications
Ad Inserter
UpdraftPlus - Backup/Restore

OpenLiteSpeed use disk caching (ram is not used for caching)

It is fine, normally use “htop” command or “top” command for more accurate memory usage statistics.

For “htop” you need to install first

yum install htop -y

thanks now i can see memory usage of everything

and one last question can it handle 100+ concurrent connection… i will live my site once i can confirm that it won’t go down anymore

There is no way to tell that for sure, it depends on various factors. But if the cache is setup correctly you should not be having issues. To be on the safe side I recommend you to run benchmarks on your website.

On a separate server you can setup apache bench:

yum install httpd-tools

Then run benchmark against your website:

ab -n 5000 -k -H "Accept-Encoding: gzip,deflate" -c 25 http://example.com/

You can increase or decrease the value of -n and -c accordingly.
