In all cases, this was with the default optimization level, -O2. Compiling with -O0 was roughly twice as fast dual core e7300 and e8400 used -j3; quad core -j5.
Does your measurement include running configure?
No, nor make depend. Nor is it cold boot, it's after 'make clean'. I didn't control whether there was a previous run, so the cache may be warm or cold.
If I run make -j5 twice after 'make clean' on my q6600 2.4GHz system and take the second measurement I get 223 seconds.
This is 64bit Ubuntu 8.10 with gcc-4.3.2 and default optimization. Or perhaps disk IO is playing a role here? I'm using a stripe set of two disks.
Yes, could be disk I/O. This system has a crappy old parallel IDE drive. (Could also be the video; this system has an internal graphics card.)

Dan,
Could you post photos and complete specs of the PW cluster somewhere? I'm curious :)
