- According to the man page for vmstat the "de" field stands for
- "anticipated short term memory shortfall in Kbytes".
-
- Mike Loukides writes in "System Performance Tuning" that a
- nonzero "de" number indicates "... an extremely severe memory
- shortage. The system is certainly performing desperation swapping."
-
- A typical output of "vmstat -S 5" for a SUN 670 - 2 CPU, 128 MB - ,
- that follows consistently shows a non zero "de" field and
- yet w (swapped out processes), so ( swap-outs) and po (page-outs)
- are always zero. Any experience with this or how "de" is determined?
