Hello 9fans,
My pc has got 128 Mbytes of RAM, but /dev/swap says
1539/19428 memory 0/19351 swap
which means, I think, about 75 Mbytes of total memory
because a page is 4096 bytes.
Where does the rest go, grabbed by the kernel?
Thanks.

I can't type, I meant 40%, not 40 meg.

The kernel is being piggy. If you have > 16 Meg, 40 meg gets reserved by
the kernel , mostly so it can use it for bitmaps. You can reduce that
by putting the following in plan9.ini:
*kernelpercent=xx
where xx is the percentage you want to reserve for the kernel.
