Virtual Server performance boost
February 6th, 2015 by pdw
We’ve just added an option to allow Virtual Servers to get full access to the CPU extensions available on the host server.
By default, virtual servers see a subset of CPU features that is available consistently across all of our hosts. For most users this has no impact on performance, but for some applications, such as performing certain types of encryption, speed can be substantially improved if certain processor extensions are available.
We’ve noticed significant improvements in OpenVPN throughput and latency after turning on this option on some of our servers.
CPU mode on our virtual servers can be configured using the “cpu” command on the admin shell.
