[tor-relays] optimize performance of a relay running on a VM

I have multiple relays running on the following systems:
- - vmware vsphere virtualization technology
- - 100 mbps port
- - 1GB dedicated RAM
- - 2.6 Ghz 1 core CPU dedicated
- - OS: FreeBSD 10.0 Release amd64 or Debian Stable
- - DO NOT KNOW IF I HAVE AES-NI SUPPORT OR HOW TO ACTIVATE IT (?)

Currently atlas shows 3-4-5 MB/s advertised bandwidth for these
relays. Arm shows between 600 and 1200 concurrent circuits (total of
inbound, outbound and exit) and average traffic consumption is 5-6 TB
per month (total both download and upload). I think this can be
improved, but how?
The servers have only purpose Tor, there is nothing else running on
them and there is no bandwidth cap or throttling.

Suggestions? Thanks in advance.
