My experiences have been pretty good in general. Most of the time no lag or issues, but occasionally I get the "system time changed or server overloaded" error. This error is very serious- eventually it brings my server to its knees, and a reset drops the ram and CPU usage to 1/5 of what it was. Only one or two griefers, but overall it's been a really fun day.
