   Running h2load with command `h2load --warm-up-time=10 -D 20 -c 4 -t 4 -m 4 https://127.0.0.1:9090/0`, this is what I get before and after the change, there are some improvements, but the difference is very minor. Both with `CONFIG proxy.config.exec_thread.limit INT 16`. However I'm not sure how the `tls-perf` is used in the original test mentioned in #7373.
