Well, looking at our bespoke logging system in PHP handling some 15-20+ million log entry's per day on a virtualized dual-core system... it's mostly disk I/O on the underlying MySQL database (currently duplicating to Clickhouse where we'll eventually store everything). And that is central application logging for about 100 servers (think syslog), some 400 "microservices" (parts of a larger application), and a handful of backend systems.

We're running out of disk space earlier than that PHP is a bottleneck here.
