The current set of results I am about to show were on an SS10 with one
142MHZ HyperSparc processor. Using the on-board Lance ethernet and
all of the server stuff on it's internal 500mb slow scsi disk. This
machine is running stock SparcLinux-2.0.29 + ISS test3 which went out
today. The benchmark client programs were run on 3 SS20's running
SunOS-4.1.3_U1, each of these have 2 50Mhz SuperSparc processors in
them. The web server used was the latest Apache release, compiled
from stock sources.
Essentially, I still believe that there are two problems with these
runs:
1) The 10baseT is saturated completely, it is limiting how
much further I can push the server.
2) I need to add more clients to get more meaningful results
under extremely high load, I'm going to try and get a run
using 20 machines or so, with 16 clients going on each
machine to see what that does. Preferably I'd like to run
all of this over 100baseT, but I lack the facilities
personally to do that at this time.
3) I also need to run a more coherent set of runs with the
recommended client distributions and time lengths from the
WebSTONE home page.
Nevertheless, have a look, this is Linux "Internet Shit Stirrer"
coming at ya:
WEBSTONE 2.0 results:

So, someone who knows something about these things, tell me do those
numbers suck raw eggs or what?
