Dawid Weiss commented on LUCENE-9286:
-------------------------------------
Only time is relevant here - it's the wall clock time of a given block of
code's execution. The rest shows percentage of overall "job" time and offset
since the start of the first task - I used our console reporting utilities
because it was simpler for me to copy/paste but you can definitely change it
into something else.
I didn't do any special warmups or anything so the above times should be taken
with a grain of salt. But they do reflect what I see in our production system
as well (and you can add a warmup round if you wish).
If you have a spare cycle, given the bizarre circumstances, please go ahead and
have a look. I'm working on something else at the moment and can't devote much
time to understanding why this slowdown takes place but I'd be interested in
any findings!

> I see a dramatic increase in the amount of memory required for construction
> of (arguably large) automata. It currently OOMs with 8GB of memory consumed
> for bit tables. I am pretty sure this didn't require so much memory before
> (the automaton is ~50MB after construction).
> Something bad happened in between. Thoughts, [~broustant], [~sokolov]?
