It should be precisely 3 times slower under that load (although low cpu using things like audio wont be affected by running 3 times slower). If it feels like much more than that much slower, there is a bug there somewhere. As another reader suggested, how does it run with the compile 'niced'? How does it perform with make (without a -j number). > This is on a Pentium-M 760 single-core, w/2GB SDRAM (notebook). What HZ are you running?
