See original GitHub issue

As far as poking around can tell, SystemInfo.hostname() is invoked only to satisfy when http2 is in use and a client or server didn’t set the authority/hostname key. At the moment, this literally invokes a shell command, slowing server startup, by default.

2019-10-21 20:48:57:164 [main] INFO SystemInfo - Hostname: macbook-pro-8.local (from 'hostname' command)

PS “1/3 (500-600ms) Armeria” isn’t to say it is spending too much time, almost all of our slim server is armeria. It is an interesting idea to see if zipkin slim could get to 1s, but in this case unless armeria can produce negative startup time, reducing here is not enough.
