Re: weird kernel/ps interaction

[Jonathan D. Poole]

Does cat /proc/cpuinfo | grep bogomips report Identical or slightly off
mips for the cpu's?

cat /proc/cpuinfo | grep bogomips
bogomips        : 399.77
bogomips        : 400.59

# date ; sleep 5 & ps -e --format "lstart cmd" | grep 'sleep 5'
Fri Jun 30 09:42:48 EDT 2000
Fri Jun 30 04:22:57 2000 grep sleep 5
Fri Jun 30 04:22:57 2000 sleep 5
9:43am  up 10:40,  1 user,  load average: 0.00, 0.00, 0.00

Mine looks quite simular
