The following is free output from a native lpar, SLES8 64-bit system:
total used free shared buffers cached
Mem: 8186328 8140748 45580 0 239356 4173208
-/+ buffers/cache: 3728184 4458144
Swap: 19231808 4762584 14469224
On the occasion when my SAP application gets backed up, it seems like the
swapout is busy. I would think that if I were swapping, the number of used
buffers/cache (3728184) should be a lot higher because the active pages
should eat into the inactive ones. But I always seem to have a lot of free
buffers/cache. Am I thinking about this wrong? For a 2.6 kernel, it looks
like swappiness might have an effect on this ratio. Is there anything that
can influence a 2.4 kernel?
