I also guessed that this might be the reason before the results came.
Now it is pretty certain, especially when we also note that fork() has
a higher penalty on OpenBSD compared to Linux.

Quark is actually very lean and offers 99% of the features you would
expect for a static server. I personally am a big fan of OpenBSD's
httpd and will use it on the server I am currently setting up.

I see quark's role more like a "drop-in" server you can invoke
literally in seconds from the command line to share some data on the
network. In this form, it is not so trivial with other servers. For
"settled" servers with a fixed configuration, OpenBSD httpd works
flawlessly in my opinion!

However, OpenBSD's httpd is not available for most Linux distributions,
and that's why quark also has some features to set up simple servers
with it that can even serve multiple hosts at once. Surely we can
discuss if we need virtual host support and whatnot, but most
"complexity" in quark is a deliberate focus on data structures to make
modifications very easy. An example is the cgi-patch[0] that is pretty
