RedHat, CentOS, Ubuntu, Debian, (Open-)SuSE as well as all Distributions with good perl
integration are performing well. There are/were some issues if you use specific
distributions and their online repository, but if you install from source
or rpm (and follow the install.md) it should work + perform fine!

How many concurrent users do you have, and what is your (virtual) hardware settings?
