[dpdk-dev] Performance regression in DPDK 1.8/2.0

[Paul Emmerich]

Hi,

sorry, I mixed up the hardware I used for my tests.

The CPU frequency was fixed at 1.60 GHz to enforce
a CPU bottleneck.


My original post said that I used a Xeon E5-2620 v3
at 1.2 GHz, this is incorrect. The calculation for Cycles/Pkt
in the original post used the correct 1.6 GHz figure, though.

(I used the E5 CPU for the evaluation of my packet generator
performance with 1.7.1/2.0.0, not for the l2fwd test.)


Sorry for the confusion.
