Limits Explained

You can apply 4 type of limits, and they are explained below.

CPU Percentage

Amount of CPU a certain website/user can use. On a Multi-core system user will get assigned share on each CPU Core. But CPU usage calculation will be divided by total cores on system. For example if website is assigned 10% CPU on a 4 core system, they will get 10% share of each CPU core.

If website start using 10% CPU on all 4 cores the average usage will then be 10% (40 / 4 = 10%)

Memory

Memory usage specifies the amount of RAM the website can use. User processes may be killed by kernel if they try to allocate more ram.

I/O

Disk I/O speed allowed for the website such as 10MB/s. This limit is not the same as IOPSĀ  described below.

IOPS

IOPS is different compared to IO, this specifies number of IO operations that a website user can do per second.

Network Speed

This specifies upload/download speed of the website user.
