here is with batch_min 400 and clone 1: 184251pps 88Mb/sec (88440480bps) errors: 0 A bit better than without cloning, but that might be a noise. batch_min 0 and clone 1: 258564pps 124Mb/sec (124110720bps) errors: 0 Noticebly better than with cloning, but still much worse than mainline. > > > mainline (the same script, on start it wrote about unsupported batch_low > > > parameter: > > > 497520pps 238Mb/sec > > > > > > And here is with batch_low=400: > > I am going to get rid of that batch param - it doesnt seem to matter > what that value is in the long run. Hmm, with that parameter result is 87Mb/sec while with batch_min equal to zero it is 115Mb/sec. Without batching result is even better - 238Mb/sec, so it does seem to affect performance. > > Result: OK: T4143884(U4143864+I20+A4007752+T127073) usec, P1000000 > > TE8511TS1(B60,-1frags) > > So on average you have been sending about 120 packets per batch - which > should give you decent numbers.
