On: Go: Functional Options Are Slow

[wbl]

If you are trying to shave nanoseconds off an RPC you have architectural issues.

[jeffbee → wbl]

If you approach every program with that attitude you will never have an RPC subsystem where nanoseconds matter. You will be trapped in a self-fulfilling process where nanoseconds don't matter because the system is slow.

It's physically impossible for nanoseconds to matter for remote calls - most individual servers are larger than one light-nanosecond.

[jeffbee → lmm]

The efficiency of initiating the call limits how many calls the program can initiate per second, per thread. The potential latency of the response is irrelevant.
