Description Bill Nottingham 2005-03-23 17:36:53 UTC 
Description of problem:

Laptop with 1.5GB of memory.

When using 1191.FC4, cache is not effectively used. 

LowFree is 8-12MB
HighFree is 312-400MB

and cache is constantly being evicted (for example, open mailbox A. Close it,
go to a different mailbox. Go back to A. A is no longer in cache.).

Going back to 1177.FC4 makes things much better:

...
Cached:         295248 kB
SwapCached:          0 kB
Active:         179756 kB
Inactive:       256464 kB
HighTotal:      654720 kB
HighFree:       239616 kB
LowTotal:       899440 kB
LowFree:        456008 kB
