If your backend is Redis, how is starting more speculative hits to Redis going to help, since it's single threaded?

I mean if this is indeed helping it seems that it's not Redis that's the long pole, but maybe the request routing mesh or something.

Variations are probably caused by TCP IMO

Wonder if for certain requests that are guaranteed to return smallish data sizes, having Redis support UDP would make sense and remove the TCP issues ...
