The benchmarks won't run at all unless all of its prequisites are
installed, so it would seem like that isn't the issue. Look at what is
happening during the runs to see whether the test is CPU bound or if the
communication has been disrupted. Hopefully, it is CPU bound as then
finding the offending bottleneck will be a lot easier; otherwise there
is a bug in the stack causing the requests to go missing.
