23+79k -- Average resident sizes of text and data+stack. The numbers
are measured in 512-byte pages.
3+0io -- This is the I/O charged to the process (not necessarily
initiated by the process). The 3 is the total number of
requests, the 0 is the number of disk accesses. The
difference is the number of buffer cache hits.
2pf+0w -- The 2pf is the number of page faults that required disk I/O
to read the page (known in unix as major faults). The 0w is
the number of times ths process was swapped to disk.
