Yes, however I don't think it did too much as I was using a DPT RAID card with
(2) 4 gig Seagate Cheeta drives in Mirror and 32Megs of cache on a 266MHX Pent I
I system with 256 Megs of memory as the requestor. The "server" was similiarly o
utfitted.
I now have it set up on an ABIT BX chipset MB with a 400 MHZ Pent II cpu.
I was thinking of using "bing" for wire speed. But my biggest problem is how to
load test it. Like pretending that the other end is and NFS mounted drive and y
our end is a well visited web server or mail server. that sort of thing since th
at would be most peoples application. Just measuring the time for a ping packet
is kinda useless and even bing just does the same sort of thing I think.
Does TTCP do any loading? anyone know where to find a copy I can compile?
My next alternative, which I know would not please my boss, is to capture a bu
ng of porno pics from usenet, and place them on a drive on system A. Then set up
a web server on system B with system A NFS mounted. Then advertise a free porno
website, and watch the traffic build ;> Of course, this is still limited by t
he fact that the Gigabit hub is connected to the router via 100Bt so even that w
ould not be "real" test :<
