Hi,
I'm new to the list and I'm having some problems measuring the performance
of a NetCache 760.

I'm using the following parameters:
./polysrv --goal -1:2min:0.03 --port 8080 --verb_lvl 3 --xact_think norm:3sec,1sec

./polyclt --ports 1024:30000 --origin 192.168.11.105:8080 --launch_win 1min
--goal -1:1min:0.03 --log test.log --verb_lvl 3 --proxy 192.168.11.150:3128
--robots 1 --req_rate 20/sec --rep_cachable 80% --dhr 0.55

I always get the following errors in the NetCache-Logfile:

lr --in test.log shows the following:

  61.03      0| p-meas      0   0.00  -1.00 217

Can anyone tell me, what I'm doing wrong ??

Using a squid-proxy everything works fine with this configuration.

Thanx,
