G6 has almost no 'idle' impact on server performance.

Without being present to be able to check the profiler during events that cause this issue, I can't make any claims as to what might be causing it, but one of the most significant sources of lag during events was the loading of event mobs, which had a gigantic performance fix applied in one of the updates earlier this year.

What I suspect could be impacting server performance in general is large or frequent I/O calls, typically from people having huge banks or savefiles, or from having to save thousands of farm plots (which I am relatively sure I did a round of optimizing not so long ago, but.). Again, I haven't really been online to monitor the profiler in recent memory.
