Hi all,
Just a quick benchmark on 8.0 Beta2+ (18/08) show no regression vs 7.2.
Result in FPS for 64bytes frame using Breakingpoint Elite
Breakingpoint P1 === DUT === Breakingpoint P2
Stream1 : P1 -> P2
Stream2: P2 -> P1
GENERIC kernel + netisr.direct
4.11 : 236 (with 1 stream down for unknown reason)
6.3 : 248
7.2 : 350
8.0b : 352
POLLING kernel + netisr.direct
4.11 : 526
6.3 : 246
7.2 : 230
8.0b : 330
Note that the perf grow a little bit from version to version but 4.11
with polling is always a lot better.
There is a lot a more in depth testing to do (HW flow tag, 10gb, lot
of interface, latency ...) but it give a rough idea of the perf in the
forwarding area.
Regards,
Fabien
