high memory consumption and slow speed
Running Libranet 2.8.1 (a commercial version of Debian) on a dual boot system. I've been trying to speed up the rather slow performance. Using some of the info in other threads, I have discovered:
Regarding hdparm, using_DMA is turned on.
top tells me that I have 320M of memory available (fits what I know about my physical system, having just installed more mem when I installed Linux), and 245M are used (thats about 75% by my calculation.) But when I add up all the %MEM column, it only adds up to about 17%
ps aux reveals similar discrepancy: adding the % mem column gets me about 50%, not 75%.
The largest percent is Mozilla, consuming about 10%
Where has all my memory gone?
