Also, it is severely memory constrained and is probably swapping mightily during these compiles. FWIW, I have noted that this is very much a CPU-bound problem. Doing the work on faster drives - like SSDs - seems to not make much difference on a given machine. -- ---------------------------------------------------------------------------- Tim Daneliuk tundra@tundraware.com PGP Key: http://www.tundraware.com/PGP/
