Excessive Lag with a space station

[StarStreak2109]

Hi there,

I run KSP with 8gigs of RAM on a pretty beefy graphics card NVidia GTX590M (for a notebook anyway) on a notebook with an Intel I7 processor. Normally I get around 80 FPS in KSP. Now, I have this space station, around which I have excessive lag. Now I know, that a station with 300+ parts will not give me 80 FPS, but not less than 8...

I suspect that there is something fishy going on, but I cannot find the source. I assume it has to do with the following error/warning showing in my log file:

Any ideas, how I could make any progress in finding the source of the lag (other than too many parts in a space station)? Thanks in advance!
