Hi Fridolin, I assume that's only 1 Plack instance on that 1 machine though, yes?

We added a nightly reboot (made by logrotate) of starman for security. Page processing goes from 2 seconds without plack to 100-200ms with it, not the search pages of course because they depend on Zebra request time. We use 2 or 4 workers on a 4 CPU machine. We used 8 workers on a 4 CPU machine once for a library with a lot of accesses.
