Hi all,
Can anybody explain this to me please.
I have 1.5GB RAM - dmesg (boot -> append="mem=1536M"):
639MB HIGHMEM available. 896MB LOWMEM available.
I have 2GB swap:
Device Boot Start End Blocks Id System /dev/hda1 1 244 1959898+ 82 Linux swap
I have no issues on this - works GREAT. Normally, after a reboot, and over night after logrotate/updatedb etc. run, I end up with about 200MB free RAM that is used/reclaimed. very rarely do I hit disk swap at all (building KDE usually grabs about 100Kb, but that is infrequent).
Last week I bought my first DVD player (yes, I know, I am late to the party!). When I watch a DVD (Xine), memory usage hardly goes up (no swap ever used). But after finishing, I then see memory usage is way down:
nick@linuxamd:nick$ uptime; free 21:11:26 up 1 day, 4:57, 1 user, load average: 0.06, 0.10, 0.26 total used free shared buffers cached Mem: 1556216 411144 1145072 0 28408 236704 -/+ buffers/cache: 146032 1410184 Swap: 1959888 0 1959888
Why is this?
Thanks,
Nick
