This is just for manual bench tests for now, to ensure a change doesn't cause a performance regression. Adds the following nixops commands to reproduce some bench tests: Note: All of the nixops command need to run on the nix directory (`cd nix`). - max requests for the nginx server: nixops ssh -d pg_net client vegeta-bench-max-requests It's capable of handling ~12k req/s. - reference bench test with the vegeta http client, only using one thread/worker: nixops ssh -d pg_net client vegeta-bench-max-requests Vegeta is able to do ~2.5K req/s. - With a pg_net.batch_size=32000, this uses pg_net for the bench test: nixops ssh -d pg_net client net-bench pg_net reaches 400 req/s max before request errors are reported. Like `Couldn't resolve host name` or `Couldn't connect to server`. These need further investigation, for now keeping the batch_size low is necessary for stability.

Adds the following nixops commands to reproduce some bench tests:
Note: All of the nixops command need to run on the nix directory (
cd nix).max requests for the nginx server:
It's capable of handling ~12k req/s.
reference bench test with the vegeta http client, only using one thread/worker:
Vegeta is able to do ~2.5K req/s.
With a pg_net.batch_size=32000, this uses pg_net for the bench test:
pg_net reaches 400 req/s max before request errors are reported. Like
Couldn't resolve host nameorCouldn't connect to server. Doing 1000 req/s or higher results in a higher percentage of errors.These need further investigation, for now keeping the batch_size low is necessary for stability.
