We have a need to simulate ~2000 interactive logins on an 8400 for a customer benchmark - nothing complex - the customer merely wants to see 2000 incoming telnet connections which (as they login) will run a copy of the benchmark code Has anyone any thoughts/experience they could share? - especially on this many users As things stand, we have a pair of 4100's that we can use as load generators It would seem practical to either use Tcl/Expect or the RTE referred to in 4251.9 (or maybe the RTE referred to in 3361.4??) to just create ~1000 per 4100 - given that all they have to do is login and direct any output to /dev/null - all timing results are being handled by the customer code running on the 8400 (and yes, I realise that by running all that timing stuff etc etc on the 8400 we are not really simulating the real user load, but the customer is insisting (and treating the competition the same)) thanks for any thoughts Brian Jarman - Technical Support, Adelaide, South Australia

Contact one of the benchmark centers, see what they use and whether
they might be available for use elsewhere.
Once upon a time I had a benchmark center list, but it's pretty out of
date now.
LABC::BENCHMARK ! US Tim Carlson 535-4011
HERON::SERV_BUREAU ! France 828-5246
mts$::"bbp:: Paul Rowell" ! UK Paul Rowell 841-3980
VICKI::RODENHISER ! System Eng John Rodenhiser 285-3362
TKOV50::Nakano ! Japan Mamoru Nakano
A better starting point is probably

Well, the UK benchmarking centre is still here and so am I!
We have used PRTE, originally written by Ray Wallace, who has now moved
on to other things. I think the group that he was in is working on a
new tool that will run on NT.
The UK benchmark centre has also developed a new tool that runs on NT
and supports connections via Winsock so we can do Telnet and anything
else that connects using IP sockets eg SQLnet.
As you are in Australia - I'd be willing to fly out and help if you
pay!!

Well, RTE written by Mr Jussi Maki is pretty easy and good tool, and of course I'd be ready to help you on-site if needed ;-) Pointer was in 4251.9 as you mentioned. We've tested 8000 scalability in several cases with this tool, and I have seen IBM and HP using this tool in their international benchmark centers. | |||||
