This really ought to be checked on a Pentium M as well, though.
Ok, my notebook uses a Pentium M 725 (Dothan).
I've run the following script (it should be equivalent to yours) with
2.6.38-rc7 from experimental in recovery mode, both for 486 and 686.
Attached you can find the results.
#!/bin/bash
for i in {1..3}; do
netperf -H 192.168.10.1,4 -t TCP_STREAM -l 60
netperf -H 192.168.10.1,4 -t UDP_RR -l 60
done
The differences between 486 and 686 look very small, if not null.
If you want me to do some more tests, i'm available.
I've seen in the beginning of this thread you've reported the result of
a scripts elaborated by a program called ministat. I admit i've not
understood well neither the results nor the procedure. If you want me to
do that as well, please, explain a bit more the procedure.
Otherwise we can try to use some benchmark tools (no experience in this
field). I've seen that Phoronix is in Debian since few days.
Ciao.
Cesare.
