Some of you might knows that OpenBSD7.6 just come out couple of days ago, I wonder if anybody tried to build the last version from source on it and can share the experiences here.
The binary version is dreadfully old.

zabbix-web-3.4.7.tgz
I had a similar NetBSD based Zabbix server
Don't remember where did I get the binaries back then but did not compile it on my own
It's sad to see that BSDs slack so far behind Linuxes with updated packages so I'm not sure it worth torturing myself to try to get it compiled because even if it does manage to run it the performance/db performance can be dreadful compared to a Linux setup.
For example take a look at this: the beginning of the chart was my old server (KVM vm exact same specs, then I switch over to Linux boom).
