Eclipse starts 15 to 20 seconds faster for me when I start it like so... eclipse -vmargs -Dgnu.gcj.runtime.VMClassLoader.library_control=never This is because it's doing over 60,000 fewer failing file-system calls (trying to open non-existent libraries). Should we change libgcj's default behaviour? If not, adding -Dgnu.gcj.runtime.VMClassLoader.library_control=never to startup scripts like /usr/bin/eclipse seems like a good idea. AFAIK we don't rely on this old class loading trick. AG
