Web Hosting Talk : Web Hosting Main Forums : VPS Hosting : VPS cPanel - Odd RAM Reporting?

[SajanP]

One our VPS cPanel clients seems to be causing my eyebrows to raise a little. Don't know whether it's a bug...or it's possible.

OpenVZ
cPanel Installed, licensed, running with 10+ accounts I think. Few Wordpress sites as well.

Solus is showing RAM usage at sub 200 MB.

Should I look into this? I've NEVER gotten cPanel to run with THAT low of a memory footprint. At least, I don't think....

[ARPLink]

Form my experience, CentOS+cPanel on OpenVZ usually eats up around 350 MB of RAM Memory. Maybe it's just a glitch in the report. What does top say on that VM?

Staring at the terminal for about 3 minutes after running top...it too shows mem usage between 201MB-205MB.

Made sure cPanel was indeed installed. Even logged in (it's a managed server) and saw that he has 11 cPanel accounts, all with active websites. 5 Wordpress.

*One thing I did note was what for 7 of the 11 cPanel accounts and many of the addon domains...the server was not being used for mail exchange.

Does offloading MX really improve mem usage by that much?

Well I have cPanel/WHM running on CentOS on my VPS as well and the memory print there is:

Memory Used 44.60% (467632 of 1048576)

And it does run email service for several domains.

Yeah, that seems a more reasonable number. What I'd normally expect.

[ARPLink]

It may be possible to reduce memory consumprion by outsourcing the mailserver. And since the databases are probably small, mysql doesn't eat up a lot either.

Could you paste the results of free -m and top ordered by memory consumption?

Looks ok. Just to be safe I'd keep monitoring it for a few days, but other that that, it looks ok. Maybe the user did some tweaks to the OS template and shut down some nonessential services.

Yeah, everything does look okay. You can understand why I did a quick double take this morning though, . Thanks ARPLink.

I will be keeping an eye on it. If he's able to optimize WHM/Cpanel like this...I might need to call him and hire him, lol.

[ARPLink]

Don't mention it . You'd be surprised what some VPS clients acomplish with some free timpe and ambition . I saw some cases where they stripped a template and it ended up consuming less than nothing. But then again, the VPS had 256 mb of RAM Memory .

[Hsunami]

From my experience, cPanel VPS optimized actually has a rather low memory footprint. It looks like you're running OpenVZ so it's not a direct comparison, however, when I installed cPanel on a Xen VPS, it was hovering around 90 MB. Keep in mind that OpenVZ reports allocated memory whereas Xen shows actual memory used.

cPanel claims it uses less than 100 mb with the VPS optimized version. I've certainly seen it come close when you get down to optimizing a lot of features. So what you're seeing, definitely looks normal.

Our cPanel provisioned VPSes are around 150MB on OpenVZ. You have to tune your stack size for processes like named which looks like it was done on this specific VPS based on your top output.

Now that's the perfect VPS client: one who uses negative memory.

"Provisioned three new clients and now we have a gigabyte MORE memory on the box."

HAHA.
