top display
I have a question about top. It's running in another window at the moment.
Here is the summary line for swap:
Swap: 128484K total, 0K used, 128484K free, 107692K cached
And here's the line for the X process, along with the header row:
PID USER PRI NI SWAP RSS SHARE STAT %CPU %MEM TIME COMMAND
485 root 11 -10 64M 21M 2448 S < 0.0 5.7 1:16 /usr/bin/X11/X :0
Most of this is straightforward enough, but:
1. How can X be using 64M of swap when the summary line says 0K is used?
(The 'free' command agrees with this, btw.)
2. What does the summary line mean by "107692K cached"?
3. Is it really normal for X to be using up 85M of memory? The system
has only been up about an hour and a half, so this isn't a slow leak
that's been building up for weeks.
I'm running XFree86 4.1 on a custom-built 2.4.7 kernel, for whatever
that information may be worth.
I remember looking at top just a few days ago, running XFree86 4.0.3,
and it seemed to be using only around 50M then (when the system had been
up continuously for several weeks). Is 4.1 really that much more of a
memory hog?
