Sure:
0.574u = Time on CPU in user mode
1.357s = Time on CPU in kernel mode
0:03.12 = Wall clock run time
61.5% = Average CPU utilization
44+199k = Memory utilization -- 44 blocks, using 199KB
278+1io = I/O utilization, I think it's the number of I/O syscalls.
13pf+0w = Number of page faults the process caused. (The VM defintion of
page fault, that is; this is not an error.)
This info is pulled directly from the system resource utilization
structure rusage, so see the getrusage(2) manpage for detailed
explanations.
