I&#x27;m disappointed that &#x27;prefork&#x27; version of fasthttp failed to run due to unknown (yet) reason. TechEmpower should publish benchmark logs later, so the problem with fasthttp in &#x27;prefork&#x27; mode could be fixed in the Round 13.<p>Fasthttp starts distinct server process per CPU core in this mode. This should result in perfect scalability on multi-CPU machines.
