- |If a machine swaps out amd it needs more RAM anyway. One of our machines, a

- |"swap ins" / 10000, I suggest adding memory.

- I have 48M on board so I doubt that this is really the root of my problem:
-
- 60-tim@crash:amd/amd>vmstat -s|grep swap
- 48913 swap ins
- 0 swap outs
- 39080 pages swapped in
- 39268 pages swapped out
- 1548 swap text pages found in free list
-
- I have patched amd anyway to see whether it helps any. BTW, to all
- amd-ers out there: do any of you nice the process up or down? How does
- this affect things?
-
- |Btw, are you running tmpfs ?
-
- Yup.

- Tx. [sorry for the delay in following up, I have been out of the office]
