First of I'd like to point out that this is not one of those other
complaints about Vista using much memory, rather I've observed some
behavior of Vista that I find a bit odd.
After having been running vista for some 5 days now (since last remote
that is) with my normal usage patterns and with the applications I
usually run (1) my memory-consumption (Commit Charge) has risen to about
1.5GB. However summing up the memory used by all running processes gives
me only some 370MB which means that the rest is used by file-caches and
what not (2).
Now as I said I'm using this computer as I usually do but under XP the
memory-usage never reached this high during normal operation. At it's
highest it would go to some 7-800MB. Considering that Visa uses more
memory in general (more features and all the debug-code etc) I'm aware
that I can not expect the same (not yet at least). But now we are
talking about a memory consumption twice as big as XP's, and most of it
is not applications.
I've heard somewhere that Vista is supposed to release memory used by
caches and such when it is needed by other applications (as any sensible
OS would do) however in my opinion it does not do it fast enough.
Since I only have 1BG or RAM that means that 1/3 of all virtual memory
resides on a pagefile and I'm experiencing a very noticeable slowdown of
the system: it becomes sluggish when switching between applications,
especially after the computer has been idle for a long while. I suppose
this is because the unused applications gets swapped out in favor of
file-caches for files transfered over the network (this computer serves
files to other computers in the house in addition to being my main
computer for daily usage).
So my question is if anyone else has experienced (what I'd call) an
abnormal amount of memory consumed by non-application data? Does anyone
have an explanation of this behavior?
1. I use Vista as my primary computer and all my daily computer-usage is
done one Vista, after all I'm evaluating the OS I'll be using after XP.
(And yes I'm aware that this might not be the best of ideas but I've got
my back covered with backups etc.)
