On a same machine, Hermitux's performance varies strongly across Linux kernel (host) releases. With older kernels such as

$ uname -v
#1 SMP Debian 4.19.171-2 (2021-01-30)

Hermitux/Redis performs at around 200K req/s (GET). With more recent releases such as

$ uname -v
#1 SMP Debian 5.7.10-1~bpo10+1 (2020-07-30)

Hermitux/Redis seems to quickly drop connections; in my case redis-benchmark does not terminate.

Hermitux/Redis runs with minifs, on the latest master.
