Yeah I was involved in a high performance DHCPv4 project.  During benchmarking we found that systemd had inserted itself into the path of syslog.  We were using syslog to log lease events.  Whilst radiusd was ~40% cpu, systemd had pegged a core trying to process all the log events.  We couldn't find a way to disable it nicely.
