High Latency on locally hosted vanilla server.

[takker 0]

I got the Mangos server up and running. This I do to be able to learn new rotations on my feral druid. All works fine. Only problem is. I some times get higher latency than I do on servers like Northdale. I get ping from 500-900. While hosted on same pc. windows 10 with 2GHz intel quad. and 16gb of ram. Any idea what could be the problem?
