Just had a look at three community-maps:
TC_Zoetemeer, TC_Monument, TC_Phelengton
Monument's texutres are broken...
TC_Phelengton and Zeotemeer get rather bad readings on the profiling tools, even Kagoshima is better...
see attachement, Palisades as reference, one thing to note tho, on Kago that is one of a few spots where performance is that bad, the community-maps have such bad performance almost everywhere.
For those who don't know what to look for, have a look at the Renderer time, something between 15-25ms is normal for official maps, anything above 30ms is going to cause problems for me.
It's hard to pinpoint the reason, but I suspect that not much thought was given to optimisation for the community-maps.
