Any way to force a delay on requests?

This might be a very niche use case for verdaccio, but I would like to use it for benchmarking npm install tests in a consistent fashion.

I'm testing the benefits of optimizations to dependency install workflows and I would like to avoid inconsistent network timings in my benchmarks. But I don't want to completely ignore network latency. I would like to run my verdaccio server with some sort of forced latency so that I can consistently measure what the impact of different optimizations would be for an "average" install.

Sorry if this is already easy and I'm just missing it.

I've read nginx has tools for that, have you researched anything in that direction?

Thanks for the suggestion! I was hoping to avoid adding an extra service for the testing, but that may be the best course of action.

While I would also initially suggest to use a "throttling" reverse proxy in front of your verdaccio instance, you could also try limiting a Docker container's bandwidth (assuming you are running verdaccio inside a container):
