FreeBSD VPS v3 Resource Allocation
If you compare FreeBSD VPS v3 resource allocations to those of Linux VPS, you may notice what appears to be a difference
in the memory limits between the two platforms. Please note that the two operating systems (FreeBSD and RHEL) use
memory differently, the values are measured differently, and the FairShare technology used to shape memory usage is
different on the two platforms. Additionally, the Web host has tuned the two operating systems to provide equivalent
performance with our applications on each platform. In other words, even though actual values are different, the
performance will be equivalent for equivalent plan types (Starter, Basic, Pro, and Pro Plus) and configuration on
each platform.
As mentioned previously, there are several FreeBSD VPS v3 plans, as in the following list:
- Starter
- Basic
- Pro
- Pro Plus
The plans utilize FairShare Technology as well as operating system-level virtualization to allocate server resources.
There are six important aspects of the resource allocation described in this document, as follows:
- Disk Space – Determines the maximum number of gigabytes (GB) of data you can store on your FreeBSD VPS v3 account.
- Total Processes – Determines the maximum number of tasks (both active and inactive) on your FreeBSD VPS v3 account.
- Total Open Files – Determines a maximum number of files which the FreeBSD VPS v3 can open at a time.
- CPU Priority – Determines a maximum amount of time, relative to other plan types, the FreeBSD VPS v3 account can access the server hardware Central Processing Unit (CPU).
- Memory – Determines the number of megabytes (MB) of memory allocation that your account provides. Use this number for capacity planning purposes.
- Maximum Memory – Determines a maximum number of megabytes (MB) or gigabytes (GB) of random-access memory (RAM) that your account can utilize.
- Virtual Memory – Determines a maximum number of megabytes (MB) or gigabytes (GB) of memory (RAM plus swap space) available to your account.
Resource parameters may be different in certain international datacenters. Please contact your account manager or visit
your local support site for the resource allocations used in your datacenter.
The following table describes the resource allocations for each FreeBSD VPS v3 plan:
| Resource Allocations |
Starter |
Basic |
Pro |
Pro Plus |
| Disk Space |
10 GB |
20 GB |
40 GB |
60 GB |
| Total Processes |
70 |

150 |
300 |
| Total Open Files |
2,000 |
4,000 |
8,000 |
16,000 |
| CPU Priority |
1 |
2 (or twice the priority of Starter) |
4 (or quadruple the priority of Starter) |
8 (or eight times the priority of Starter) |
| Memory |
256 MB |
384 MB |
512 MB |
768 MB |
| Maximum Memory * |
512 MB |
768 MB |
1 GB |
1.5 GB |
| Virtual Memory (Supplementary Information) |
(1 GB) |
(1.5 GB) |
(2 GB) |
(3 GB) |
* For FreeBSD VPS v3, Maximum Memory works as the Soft Limit. Exceeding Maximum Memory limit will cause performance
degradation.
