adamrk opened PR #14280 from adamrk:abk/guest-host-async-call-benchmarks to bytecodealliance:main:

Adds a benchmark for async lifted and async lowered nop calls between the guest and host. I'm getting:

component-async/host-to-guest
                        time:   [1.4025 µs 1.4068 µs 1.4122 µs]
component-async/guest-to-host
                        time:   [279.31 ns 280.36 ns 281.67 ns]

versus

sync/no-hook/core - host-to-wasm - typed - nop
                        time:   [27.718 ns 30.766 ns 33.759 ns]
sync/no-hook/core - wasm-to-host - typed - nop
                        time:   [7.2183 ns 7.4901 ns 7.8316 ns]

for sync core calls.
