Memory / Cpanel
May 31, 2008I have a VPS with 384MB of guaranteed ram/ 1GB burst, and my question is roughly how many accounts [each with cpanel] I will be able to fit on it, before the vps starts to slow down?

Cpanel VPS - Plenty Of Free Memory, But 'committed' Memory Exceeds VPS RAM
Jun 12, 2009I have a VPS. And have had an issue both when it was 1Gig and now I recently downgraded it to 768m, because I am moving some sites to a dedicated.
However, the part I am having trouble grasping is that when I look at graphs from Munin, it will typically always show 200-400MB free memory (and free -m and top agrees with munin), but Munin shows 'committed' memory that is above the total Ram on the VPS and once the 'committed' ram exceeds the VPS limit, processes start failing.
So, why is 'committed' memory exceeding the RAM on my VPS, when Munin, free -m and top all show there is free memory available?
Code:
root@server [~]# free -m
total used free shared buffers cached
Mem: 768 449 318 0 0 0
-/+ buffers/cache: 449 318
Swap: 0 0 0
Here's a graph that munin produces that shows the 'committed' memory exceeding the total memory.

CPanel Eats VPS Memory Or You Just Don't Have Enough
Dec 15, 2008I was told that cPanel itself eats about 128-256Mb of memory from the VPS, so if I want to have cPanel I need at least 384mb RAM to start few simple sites working.
Is it true? (I definitely need cPanel, abandon it - it's not an option)
What (as I think) require resources I need to work at the VPS:
1. Three php sites (osCommerce, MySQL, not ideal code optimization I believe, 80-180 visitors at the same time for all 3 in total)
2. One php photo gallery (20-50 visitors at the same time)
Those 4 sites generate about 70Gb bandwidth monthly.
3. cPanel.
which amount of RAM is required to get it working fast?
Memory Issue For CPanel VPS
Jul 14, 2008I purchased a cPanel VPS of 128MB RAM. Problem is that without even launching my website, the memory usage of the server is over 95%.
if shifting to Plesk will lower my memory usage? Can I deploy my site on 128MB RAM keeping in mind that site only get 6675 hits a month and is a dynamic site in PHP/MYSQL (not very complex programming though).
I want managed hosting and wont prefer upgrade as I am already paying $27 per month for it.
If upgrade is option, then can someone recommend a host under $30 with enough RAM OR will switching to Plesk save RAM?
top command on idle server with no visitors.

User Nobody Using All System Memory Cpanel
Apr 16, 2009I tracked down another issue that I am having with this same server. I login and look at the system and 100% of the swap is used and 99% of the Ram. I look to see who's using it, and the user name is Nobody. What role does this user play in cpanel? Can I disable the user?
UPDATE: It is actually apache doing it.

Aug 31, 2007I know bluehost.com "sort of" does this. If you use more then x % of the total CPU or memory of the server, then your account will be limited automatically.

High Memory Usage - Cpanel Server
Jan 6, 2007for the last few days, i am facing high memory usage up to 90%.
Memory usage get's high, even if i don't have many visitors online. I have to restart httpd to get the memory to normal. some times, server loads, get's high aswell.
In error logs (only unusual things i see):
Code:

Memory Usage :: Put More Content Into Memory?
Jul 16, 2009I just got a new server Dual E5520 with 6GB RAM, SAS 15k rpm raid10. It's running well. However, the memory usage is just around 2.5GB, even when I have more traffic. Here is the kernel info

Any idea that we can put more content into memory?
