Performance vs other crates?
A basic performance comparison would be great to compare against other rust ringbuffers, as well as crossbeam channel.
Hi, thank you for being interested in this crate!
Honestly speaking, the performance wasn't the main goal of the crate and I haven't focused on it heavily. I created that crate just to have at least some implementation of ring buffer being light-weight and with direct access to underlying memory. And I'm glad to see that now there is a variety of a ring buffer implementations to choose from.
About your question - @mgeier made a nice comparison and according to it rtrb seems to be a better option.
It's interesting to find out where 3x performance difference come from. Maybe in near future I will find some time to investigate this and to apply some optimizations.

I guess a part of it comes from false sharing of the head and tail indices as suggested in #7.
https://github.com/agerasev/ringbuf/issues/7#issuecomment-666339687 mentions another potential optimization by trying to read the atomic indices less often.
