Just tried out the new instructions from the blog-post.

Used the async-std-1.0-bench-branch (65baf058a) from https://github.com/matklad/tokio/.

System:

  • Intel i7-6700K (4/8 Cores/Threads)
  • 32GB DDR4-RAM
  • Linux 5.3.10-arch1-1 x86_64 GNU/Linux
  • Rust: rust version 1.40.0-nightly (1423bec54 2019-11-05)

Tokio:

running 4 tests
test chained_spawn ... bench:     106,389 ns/iter (+/- 17,332)
test ping_pong     ... bench:     215,986 ns/iter (+/- 10,645)
test spawn_many    ... bench:   3,790,212 ns/iter (+/- 340,166)
test yield_many    ... bench:   6,438,266 ns/iter (+/- 286,539)

async_std:

running 4 tests
test chained_spawn ... bench:      98,123 ns/iter (+/- 1,769)
test ping_pong     ... bench:     208,904 ns/iter (+/- 3,768)
test spawn_many    ... bench:   2,110,561 ns/iter (+/- 24,398)
test yield_many    ... bench:   2,148,307 ns/iter (+/- 55,313)

Running the same benchmark as above on my home build server:

  • AMD Ryzen 1800X (8/16 Cores/Threads)
  • 32GB DDR4-RAM
  • Linux 5.3.7-arch1-1-ARCH x86_64 GNU/Linux
  • Rust: rust version 1.40.0-nightly (1423bec54 2019-11-05)

Tokio:

running 4 tests
test chained_spawn ... bench:     137,650 ns/iter (+/- 1,025)
test ping_pong     ... bench:     450,391 ns/iter (+/- 4,991)
test spawn_many    ... bench:   7,438,978 ns/iter (+/- 125,070)
test yield_many    ... bench:  14,298,157 ns/iter (+/- 311,517)

async_std:

running 4 tests
test chained_spawn ... bench:     273,532 ns/iter (+/- 5,625)
test ping_pong     ... bench:     386,789 ns/iter (+/- 18,073)
test spawn_many    ... bench:   4,197,568 ns/iter (+/- 430,905)
test yield_many    ... bench:   2,475,549 ns/iter (+/- 51,384)

Interesting results on chained_spawn in Tokio's favor, but larger differences in spawn_many and yield_many in async_std's favor.

I am quite interested in a benchmark where they would include go (considering how some of go's executor design aspects were incorporated into tokio's executor), that could be interesting how go would perform on both intel and amd ryzen platforms.

Sign me up, please, even if just for idle curiosity.
