Well I did a test by compiling the 0.97 kernal (after a make clean) under both
0.96 and 0.97. I have a 386-40 with 8meg memory and ran the test in an xterm
on an otherwise idle machine (xclock was the only other X application running).
0.96 kernal
730s real 448s user 127s system
0.97 kernal
1521s real 449s user 166s system
It took twice as long, I assume this was increased disk traffic (hence the
higher system time). Is there a problem with dirty disk blocks filing
up memory?
