Subject: Re: [PATCH 0/9 Rev3] Implement batching skb API and support in IPoIB


Hi Dave,

> I ran 3 iterations of 45 sec tests (total 1 hour 16 min, but I will
> run a longer one tonight). The results are (results in KB/s, and %):

I ran a 8.5 hours run with no batching + another 8.5 hours run with
batching (Buffer sizes: "32 128 512 4096 16384", Threads: "1 8 32",
Each test run time: 3 minutes, Iterations to average: 5). TCP seems
to get a small improvement.

Thanks,

- KK
