James Wing commented on NIFI-3350:
----------------------------------
[~mosermw], how would you describe your test methodology for that speed
improvement? I have not experienced the same improvement yet. I tried this
out two ways:
1. Local Machine - where I clear out all of the repository and working
directories prior to running NiFi before each trial.
1. Docker - with a Docker container that boots up a fresh OS with the NiFi
source for each run, so no directories are preserved.
How does that compare with what you are doing?

> On NiFi startup, after seeing the new log message added in NIFI-3164, I
> noticed that generating documentation of all components takes a long time.
> After reading the NarUnpacker code, it appears to scan every file in every
> jar for NiFi component documentation. I think there are some optimizations
> we can do here which should reduce NiFi startup time.
