Still not pleasant to use the GUI with a kernel build (-j1 or -j2) happening unless the build is manually "nice'd". Also, accounting looks weird in top(1). With a 100% busy machine, top will show something like this : > top - 14:20:11 up 10:22, 1 user, load average: 2.65, 2.80, 2.18 > Tasks: 134 total, 4 running, 128 sleeping, 0 stopped, 2 zombie > Cpu(s): 68.7% us, 6.7% sy, 24.7% ni, 0.0% id, 0.0% wa, 0.0% hi, 0.0% si > Mem: 2076964k total, 2002560k used, 74404k free, 148924k buffers > Swap: 2409740k total, 244k used, 2409496k free, 1448876k cached > > PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND > 1824 root 36 10 11748 7244 1936 R 4.0 0.3 0:00.12 cc1 > 1845 root 31 0 8080 5272 1412 R 1.7 0.3 0:00.05 cc1 > 4139 root 20 0 176m 35m 6860 S 1.3 1.7 18:59.35 Xorg > 29381 root 20 0 33712 16m 12m R 1.0 0.8 0:27.24 konsole > 3 root 20 0 0 0 0 S 0.3 0.0 0:00.49 events/0 > 1529 root 20 0 2556 1460 752 S 0.3 0.1 0:00.05 make > 14623 root 20 0 2200 1144 860 R 0.3 0.1 0:00.89 top > 1 root 20 0 1568 532 464 S 0.0 0.0 0:00.22 init > 2 root 39 19 0 0 0 S 0.0 0.0 0:00.01 ksoftirqd/0 > 4 root 20 0 0 0 0 S 0.0 0.0 0:00.00 khelper > 5 root 20 0 0 0 0 S 0.0 0.0 0:00.00 kthread Mmm.. I wonder where all of that 100% CPU went to.. the busiest tasks are only showing up as 4.0% and 1.7% (when in fact they are using near 100%). Cheers
