Thread: High memory usage

chaps,

thread may quite vague i'm not sure of details of problem asking about, , not technical (i posted in beginner forum!)

running 11.04 on 3 machines, , 1 of them seems using quite lot of memory. never below 50% (not on first boot-up, no applications running), , feels sluggish use; applications slow open , close, , things moving between tabs in chromium or adobe pdf viewer don't happen instantly.

machine in question running 64-bit 11.04, , screenshot system monitor looks this:



computer running chromium browser, 3 tabs open, , yet showing 1.2gb of memory used.

know ubuntu uses memory differently way windows uses memory, , 2 aren't comparable, other 2 machines have (both of them lower-spec, both of them running 32-bit 11.04) both use less memory. (they use less memory, , lower percentage of memory have, despite having less memory installed ... if made sense.)

cpu usage isn't particularly high, , machine appears run should. it's ... sluggish. think has become more sluggish on last few weeks, , investigating sluggishness led me check memory usage. fwiw, machine has dual-core amd 5600 chip, has started feel slower lower-spec single-core x61s laptop have.

on basis, think there wrong, not sure or go looking. have searched on here , on other sites, without luck. have found program called htop, gives result:



... doesn't mean lot me, other give impression chromium using memory in lot of small bits.

welcomed. please ask if need more details system.

many thanks, in advance.
