dmesg talks about 224 MB available memory, but I am having trouble matching=
=20
this with the output of top:

Memory: 101M Act, 56M Inact, 1260K Wired, 39M Exec, 57M File, 12M Free
Swap: 512M Total, 9532K Used, 503M Free

I do not believe that Firefox is doing a lot of swapping, because the LED f=
or=20
the harddisk is quiet most of the time, and obviously there is very few=20
swapspace used.

However, I found something else (which I should have noticed before) in the=
=20
output of dmesg:

That doesn't look good, does it? Maybe my RAM is not accessed properly and=
=20
hence very slow? That would explain why memory-hungry applications run so s=
lowly.
But then I did some digging on this and found
http://mail-index.netbsd.org/port-i386/2002/10/11/0003.html
which suggest that this is normal.


Another idea of mine is that it is connected with the LongRun support. I've=
=20
read that it can be configured via sysctl. Anyone knows an example to tune =
for=20
more performance this way? Energy consumption is no problem (as long as the=
=20
notebook does not become too hot), because it is almost always connected to=
 a=20
power socket.


I include the rest of dmesg for completeness:
