I have been using eclipse for about 4-6 months with several C++ projects under linux, the performance has just gone from fast to totally un-usable. Example, it takes 5 seconds to switch buffers that are open, 10 seconds to save. Load is high CPU=255%

52760 mbetten 20 0 6408m 444m 23m S 255.8 1.9 18:15.18 java

I am on a high end system w/ 12 cores and 24G.

I am using /usr/java/jre1.7.0/bin/java for java.

It happened on two different projects where I have different workspaces. I deleted all the .metadata director for one of the project and it is still unusable. please help

Thanks



ps ax|grep java

Please open a bug against CDT and attach stack traces that show where
the time is spent.
