hello Richard, could you give me detail when it is 100 sites and when it will be 1000 sites? sorry for dummy question. -

Yes, its not easy to understand at first
At the moment 100% is all of your CPUs added together
In the future 100% will be 1 CPU
For the moment you have to decide how much CPU you want to allow each site to use (1CPU, 1/2CPU…) and then work out the percentage based on how many cores you have got.
If you want to allow 1/2 a CPU
You have got 8 CPUs
8 CPUs => 100%
1 CPU => 100/8 = 12.5%
0.5CPU => 6.25%
You can only use 1% intervals so currently you would either choose 6% or 7%
In the future you will be able to choose 50% for half a CPU. It should make things a bit easier and it will make things more accurate when we have many CPUs on a server.
Another example, if for a site you want to allow 2CPUs you would set :
Percentage : 25 %
nCPU : 2
If you want to allow 30% of total CPU you would have to set :
Percentage : 30 %
nCPU : 3
This is because 2CPUs represent 25% so to give access to the remaining 5% you would need to give access to a third CPU.Leave a comment:

hooo,
sorry that is confusing for me how to use cpu percentage.Leave a comment:

I was just saying that if you set ncpu to 1 then 12.5% CPU is the maximum you will be able to use and not 25% in order to use 25% you need to set ncpu to 2
The default setting of 25% is for smaller servers then yours.Leave a comment:

Hello Richard Hordern,
currently, I use default of clould linux which had been set, and just increase I/O limit to 5120KBps.
thanks for reply me Richard,Leave a comment:

Hi,
25% is of the total CPU ressources.
Youve got 8 x 3.3GHz theads how much CPU to you want to allow each user ?
the nCPU is how many threads each user can use, so youre actually limiting your users to 1CPU and not 25% (100% / 8 = 12.5%)
Some hosts set the limit around 1Ghz others 2 or more… Id try setting your CPU limits between 6 and 8%
The number of sites you will be able to host will depend on how much ressources each site uses.
The answer is anything between 100 and 1000 sites…Leave a comment:

asking for idea about cloud technology feed
Dear All,
Below is my fully specification of my server:
CPU 3.30GHz Core 4, Thread 8
RAM 32GB
HDD 2TB SATA III
Cloud Linux + Cpanel
Apache + php fcgi + Eaccelerator
Default Cloud configuration
CPU 25%
nCPU 1
vmem 1024MB
pmem 1024MB
EP 20
nPROC 20
I/O Limit 1024KB/s
can all of you help me to estimate
how many client could I host on this server.
due Im new with cloud linux technology.
Best Regards,
Steve.Tags: None
