| # libnativewindow Benchmarks |
| |
| This directory contains benchmarks for the C++ and Rust variants of |
| libnativewindow. |
| |
| ## Running |
| |
| It is currently a little tricky to get statistics from Rust benchmarks directly |
| from tradefed. But we can hack it by using atest to build/push, then running |
| the benchmarks by hand to get stats. |
| |
| ``` |
| $ atest nativewindow_buffer_benchmarks_rs nativewindow_buffer_benchmarks_cc -d |
| $ adb shell /data/local/tmp/nativewindow_buffer_benchmarks_cc/x86_64/nativewindow_buffer_benchmarks_cc |
| $ adb shell /data/local/tmp/nativewindow_buffer_benchmarks_rs/x86_64/nativewindow_buffer_benchmarks_rs --bench |
| ``` |
| |
| ## Results |
| |
| On a remote emulator, the results we see from the benchmarks from Rust and C++ |
| seem to be roughly equivalent! Allocating/deallocating a 720p buffer takes |
| ~2.3ms on each. |
