   Haven’t tested, but this might be faster: https://twitter.com/fedor/status/1354505744293502980

   No speed up observed?

   Strange.

   I wonder how much our tests are really bound by I/O speed. I guess it could matter for compilation times. But I wouldn’t be surprised if it’s mostly CPU bound.

   It seems this will result in a slow-down. E.g. https://cirrus-ci.com/task/6631575736549376?command=ci#L5821 vs https://cirrus-ci.com/task/5477946514210816?command=ci#L5513

   Looks like it is only using 0.3 CPU even though 2 have been requested?

    Not sure what happened in the meantime, but there seems to be a speedup now. (Also the fuzz task is passing and no longer timing out)

    ACK fa212391ce0bb04669bc5205553a71e653f5ad48 - going to merge this now given there is a speedup, and it’s enough to fix the fuzz task the is continually timing out.
