Round of perf optimization

[film42]

This library is in a really good place, but I'm always interested in making it faster. If you have experience optimizing rust code, please take a look at this repo. We do a lot of Arc cloning and data copies through the worker flow. I'm sure there are some good ways to clean that up. If you're interested, take a stab and open a PR! <3

Hi @film42 i'm just evaluating this lib. I can tell you that for your typical background jobs, the optimizations you're looking for aren't needed at this point, both from Rust's point of view, the workloads expected, and being familiar with background job frameworks that I've built myself in the past.

Thanks for evaluating the lib, @jondot ! Let me know if you have any suggestions. I agree that throughput is 👌, but once async traits become stable (hopefully by end of year) I expect a little more throughput and maybe even fewer calls to .clone() which will be nice. But, as you said, for most background job workloads, this library is already in a great place.
