Onionbalance on a single server

Is it bad or acceptable to run onionbalance on a single server to squeeze more power out of it?

I have a server with 8 cores and 20GB memory, since tor only makes good use of one core I figured I could run onionbalance on this machine, then run 6-8~ backend tor instances to make use of all cores.

Anyone have experience trying this? I won’t get redundancy but should be able to handle more connections since cpu is bottleneck here.
