Limit tokio to current thread

[Firstyear]

Hi there,

In https://github.com/pendulum-project/ntpd-rs/blob/main/ntpd/bin/ntp-daemon.rs#L5 you are using tokio::main which activates the multi-thread scheduler. On my xeon server with 24 threads, this means that I have ntpd-rs with 24 idle threads.

I would assume that setting tokio to the current_thread runtime flavour would probably be okay for the project, and also seems like a simpler/less resource consuming default?

Hi,

My 2 cents here: if the number of threads is important in the context of a highly solicited server, on simpler setups it is overkill; perhaps adding a config parameter / startup flag would be the best response for both situations ...

I'd be fine with configurable too, but I would say the default should be single thread as the majority of users of this I assume will be clients. If you're running an ntpd-rs server then it's easy to bump this up if needed.
