Re. the Fitlet: With a 3.9 to 4.5 W power budget this box will never get into those ranges, but even handling 1K requests/second with sub-ms jitter and delay would still be a very nice Pool server. A Raspberry PI can do 1500 packets per second. That's a simple measurement with one request

We were using autokey at our public ntp servers(1) since 2011. We are now in the middle of a process to deactivate it, since 4.2.8 is broken (we could not make autokey work with 4.2.8 on Linux, it seems to be some issue related to the version 1.0.x of openssl). Probably we will let it
