chore: benchmark streams against iterators #18

Closed reconbot closed 5 years ago

They're about the same when processing data! Quite the same when processing slow data! When doing nothing, passthrough is faster than tap.

tap slow source x 19.60 ops/sec ±5.07% (50 runs sampled)
stream tap slow source (PassThrough) x 21.27 ops/sec ±3.77% (53 runs sampled)
tap fast source x 81.60 ops/sec ±1.73% (74 runs sampled)
stream tap fast source (PassThrough) x 164 ops/sec ±1.06% (77 runs sampled)
map slow source x 20.19 ops/sec ±1.98% (51 runs sampled)
stream map slow source (transform) x 19.98 ops/sec ±3.62% (51 runs sampled)
map fast source x 21.42 ops/sec ±1.80% (53 runs sampled)
stream map fast source (transform) x 22.32 ops/sec ±3.18% (55 runs sampled)
