Subject: [dpdk-dev] IXGBE throughput loss with 4+ cores
Date: Tue, 28 Aug 2018 17:34:27 +0430	[thread overview]
Message-ID: <74400e6a-91ba-3648-0980-47ceae1089a7@zoho.com> (raw)

Hi,


I have run multi_process/symmetric_mp example in DPDK example directory.
For a one process its throughput is line rate but as I increase the
number of cores I see decrease in throughput. For example, If the number
of queues set to 4 and each queue assigns to a single core, then the
throughput will be something about 9.4. if 8 queues, then throughput
will be 8.5.

I have read the following, but it was not convincing.

I am eagerly looking forward to hearing from you, all.


Best wishes,

Saber
