Subject: [dpdk-users] Limitation of performance the X550(RX pps)
Date: Thu, 9 Nov 2017 10:08:27 +0900 [thread overview]
Message-ID: <001e01d358f7$4071e9d0$c155bd70$@jp> (raw)
Hi, all.
Could you tell us whether the events described below are within assumptions
?
>From server1 where DPDK was installed to server2 installed in the same way,
we sent 14.88 million 64byte-length packets with pktgen.
At first, we installed x540-t2 in server1 and server2, and next did x550-t2
in server1 and server2.
In the measurement, when the packet-length is 64 bytes, x540-t2 received all
14.88 million packets, while x550-t2 received only 4.82 million packets.
When the packet-length is 128 bytes, x540-t2 received 8.44 million packets,
while x550-t2 received only 4.62 million packets.
These numbers show the performance of x540-t2 will be better than that of
x550-t2 although, given the specifications, the results should be the
opposite.
I don't know why it will result like this. Could someone let us know why
this could happen ?, and if there is a difficult part to understand, please
let us know.
