Thank you for doing this!

One of the most fascinating things I think is how photon really shines 
when concurrency gets dialed up. With 8 workers, it performs about as 
well, but below, the rest of the micro, including below Rust and Go 

However, at 64 concurrent workers, photon rises to the top of the stack, 
performing about as well as eventcore and hunt. When going all the way 
up to 256, it was the only one that demonstrated **consistent 
performance** -- about the same as w/64, whereas ALL others dropped off, 
performing WORSE with 256 workers.
