Benchmark

Ensure that there is no CPU-heavy process in background!

```shell script cd benchmark

measure all with system malloc

cargo bench

measure only chat run

cargo bench -- "chat run"

measure all with jemalloc

cargo bench --features jemalloc

measure only simple run with jemalloc

cargo bench --features jemalloc -- "simple run" ```

Now HTML report is available at benchmark/target/criterion/report
