  "In Python, most of the bottleneck comes from having to fetch and deserialize Redis data."

This isn't a fair comparison. Of freaking course postgres would be faster if it's not reaching out to another service.

Yes, that's essentially the point being made here. It's a fair comparison if your intent is to run this kind of job as quickly as possible.

>>redhal+c7
No it's not. It tells me exactly nothing useful about the postgresml performance because it's impossible for me to rule out redis and the http server when factoring in performance. It's two hops, with a guaranteed delay that the postgres setup won't have.

If they wanted it to be a fair comparison they should have used FDWs to connect to the same redis and http server that the python benchmarks tested against.
