Research direction

Start by reading the request and identifying Redlib’s request handling and data-fetching entry points, then trace the stages from receiving a request through returning the rendered response. The issue asks for average timings across several time windows but leaves the measurements and performance view design open; done means users can inspect useful breakdowns to help identify slowdowns.

Written by the indexing model from the issue text.

Description

enhancement

Is your feature request related to a problem? Please describe.

Redlibs runs in Docker on my NAS. The typical response times range from 400 to 1500 (!) ms. I could be the weak CPU, it could be a bottle-necked connection, maybe a cache is too small or there's not enough free memory. I don't know why it's so slow because there's nothing that tells me the reason.

Describe the feature you would like to be implemented

To identify bottlenecks I would like to have some sort of performance view that breaks down what Redlib does and how long that took on average during the last 5m/15m/1h/1d. It could list Something like decoding request, contacting Reddit servers, downloading data from Reddit, format view from received data, provide user with processed data, etc. What-ever makes sense in regarding software architecture and helps debugging slowdowns. You know better than me what would be useful to show..

Redlib boasts that it is one of the or the fastest Reddit frontends. But honestly, 400+ ms response times are kinda slow.
