From df29ebfe02aa0639278527b0fa2d90074263af0f Mon Sep 17 00:00:00 2001 From: Stefano Brivio Date: Wed, 21 Sep 2022 01:21:32 +0200 Subject: test/perf: Disable periodic throughput reports to avoid vhost hang It appears that if we run throughput tests with one-second periodic reports, the sending side of the vhost channel used for SSH-based command dispatch occasionally stops working altogether. I haven't investigated this further, all I see is that output is truncated at some point, and doesn't resume. If we use gzip compression (ssh -C) this happens less frequently, but it still happens, seemingly indicating the issue is probably related to vhost itself. Disable periodic reports in iperf3 clients. The -i options were actually redundant, so remove them from both test files as well as from test_iperf3().
