Subject2.1.99 is less rusty
Date

Because of the 'mount' problems with the pre-2.1.99 kernels, I didn't
investigate the effects of the mm changes upon the performance of my
pitifully low memory machine. With 2.1.99 now released, I forced my way
around the 'mount' problem and ran my test script. I can report that
the 2.1.99 kernel appears to be significantly better than other recent
kernels in the 2.1.xx series, although it is still much worse than
2.0.33 in the rusting department...

The results from the test script which I posted to this list are:

$ ./test-compile.sh
Test gcc compile times.
Linux version 2.1.99 (root@lorentz) (gcc version 2.8.1) #51 Sat May 2 13:06:32 EST 1998
gcc takes 35.84 seconds before 'find'
find /home/sys -print | wc --> find took 23.64 seconds
15521 15521 629697
gcc takes 100.07 seconds after 'find'
find /home/sys -print | wc --> find took 23.52 seconds
15521 15521 629697
gcc takes 93.48 seconds after 120 second wait


To summarise the results so far:
kernel approx rusting effect
2.0.33 38 --> 30 (improves!)
2.1.96 37 --> 263
2.1.98 43 --> 284
2.1.99 36 --> 100

(Note that the results are not precise, there is a random variability
in the results of perhaps 5% -- but don't quote me because I haven't
actually gathered statistics...)
