WHAT IS CLOUDLINUX?
CloudLinux is an operating system that specially designed for shared hosting environment, which consists of user resources usage control. Our in-house cloud infrastructure are purposely built and optimized for daily business use. Coupled with CloudLinux, it allow our web hosting services run in stable, secure and individual account isolated environment (CageFS - Visit HERE for more information). Your website no longer affected by noisy neighbors who possibly use up entire server resources that eventually bring down your website in the same machine.
SERVER RESOURCES CONTROL
Parameters recommended by CloudLinux:
Typical hosting: CPU=100%, Physical Memory=256MB, Disk IO=1024KB/s or 1MB/s
Highend hosting: CPU=200%, Physical Memory=512MB, Disk IO=1024KB/s or 1MB/s
Following tables indicate the allocated resources for each web hosting plans:
| Service Plan |
CPU Power (%) |
Physical Memory |
Disk IO (MB/s) |
Inode Allocation (Max. Files) |
| LVE Default setting for new account creation on reseller hosting plan. |
100 | 512MB | 10 | No Limit |
| XLimit Reseller (soon) | 200 | 2GB | 20 | No Limit |
| 15G Dedicated | 200 | 3GB | 30 | No Limit |
| 10G Dedicated | 200 | 2GB | 20 | No Limit |
| 5G Dedicated | 120 | 1GB | 15 | No Limit |
| 2G Dedicated | 80 | 512MB | 10 | No Limit |
1) Speed (CPU Power)
Percentage of CPU power allocated. Eg. suppose one CPU core = 2GHz, with CPU power of 50% means you can use up to 1GHz CPU power to run your website. 100% means full one core or 2GHz. If your CPU usage go beyond the limit, your website will slow down or stop working. HOWEVER, other tenant's website remain normal.
2) Physical / Virtual Memory
Amount of memory that allocated for each account. If your memory usage go beyond the limit, visitors to your site will receive error 500 or error 503 message in their web browser.
3) Disk I/O
This parameter is the restriction of data throughput for each hosting account. When website data throughput go beyond the limit, your website will still working but at slower rate until the active data flow level lower than the limit set. 10sec burst through the limit is enabled for each account.
MY WEBSITE HITS THE LIMITS!
When your website hits the pre-allocated resources limit based on above service plans, you will observed abnormal respond of your website.
You can always login to your control panel account and look for Metrics >> CPU & Concurrent Connection Usage. You can view details of resources usage in graphical form as well as raw data for each interval.
What you can do?
1) Check your website content to see any poorly written scripts.
2) Repair / optimize your database.
3) Disable plugins or features that causes over usage of resources.
4) Order new dedicated hosting plan and split your domain(s) to different account (Since resources limit is per account basis). You can also upgrade to Reseller Hosting for the same purpose.
5) Upgrade to higher plan based on your website resources usage historical data.
