On the bright side, I’m seeing outstanding network performance on Linux, and FreeBSD, although also very good, hasn’t been able to match it in my testing so far.
For instance, my Mailguard web portal is a modest VM, running apache and php-fpm on Debian 13 in 2 GB RAM, and I am seeing close to 100,000 requests/second across the lan with small files, using apachebench.
