Subject: Soft-RoCE performance
Date: Thu, 10 Feb 2022 16:33:48 +1300	[thread overview]
Message-ID: <CAGP7Hd6PAYcX_gMMh8jbpezeSSWQxqDrYwxEq1N-zjgT7563+g@mail.gmail.com> (raw)

Hello!

I am seeing that Soft-RoCE has much lower throughput than TCP. Is that
expected? If not, are there typical config parameters I can fiddle
with?

When running iperf I am getting around 300MB/s whereas it's only
around 100MB/s using ib_write_bw from perftests.

This is between two machines running Ubuntu20.04 with the 5.11 kernel.

Cheers,
Christian
