IDEA 8.0.1 produces very high CPU load

Hi,

I switched from 7.0.4 to 8.0.1 and now have severe performance issues when working on my project. I'm working on a quite large maven2 multimodule project, formerly I did this with IDEA 7.0.4 and had no performance problems. Since I switched to 8.0.1 (I don't use the old project but reimported it), when editing a file e.g., the CPU is permanently around 40-50% while I'm typing, also scrolling around in the editor is very slow, etc. The whole user experience seems very slow, while my CPU is constantly under load. Do others have the same problems?

My system:
Ubuntu 8.10 i386
JDK 1.6.0_10

idea.vmoptions:
-Xms256m
-Xmx512m
-XX:MaxPermSize=120m
-ea
