MRVIR Thanks for all your efforts and the data.
Even though my efforts to reduce memory with RC3.7 didn't seem to make a difference I'll keep it. I'll also keep ship classes. I wish Cosmoteer developer mode would give some statistics for mods like how much memory a mod actually uses. As is we can only see all the memory the game uses at one time. It's not really precise enough.
I'll release RC3.7 this weekend. I'll also ask @Afox2 to run his test to see if it's better for him, too. Can't have enough test data.
It's too bad I still don't know where the difference is that makes Abh lag more then the combined mods of the others. My current guess is it's the large number of effects but I can't test this.
