Change 337057 had a related patch set uploaded (by Florianschmidtwelzow):
Add threads parameter to captcha.py for multithread CAPTCHA generation
Comment Actions
To generate 10k captchas, using WMF wordlists etc etc...
On a single core vm. 2299.984 MHz
real 43m31.650s user 41m54.592s sys 0m33.300s
on terbium, 6 (12 threads with HT) core E 5-2440 at 2.4 GHz
real 26m41.157s user 26m31.411s sys 0m7.561s
Will test it with > 1 thread with Florians patch to see the improvement it makes

Great, thanks @Reedy for the test. I can't await the results with multiple threads :)

Well, this is fun...

So based on this... Multi threading, at least, in it's current implementation, makes no improvement? :(
@Florian Do you have any python benchmarking/profiling tools? It'd be interesting to see what parts (of the single threaded version) is taking the time, and if there's anything we can do to improve it
I'll deploy my backport of the instrumentation to the php script, and have a look at what % of the overall time this takes....
Comment Actions
Kind of, I wanted to test it on the version we're running in production, so copied his changes to the old copy of the script to test the multithreading

Debian python3-pil package? If so, this isn't the PIL, but instead pillow, iirc. I remember, there was a change to convert the cpatcha.py code from PIL to pillow, as PIL isn't supported anymore.
... Oh no, it wasn't pilow, but a "more current version" of PIL: https://gerrit.wikimedia.org/r/#/c/231157/2

You'd probably want to use something like multiprocessing instead of threads. Threads really aren't all that useful--they use the same I/O scheduler and have the global interpeter lock. Threads technically have a slightly lower startup cost, but this is really negligible for tasks of any measurable length--most benchmarks you'll find here are pointless.
As best I can tell you're not actually needing to share any memory between these processes--everything is passed as a parameter to your function--you'd probably see a drastic improvement in moving from Thread() to Pool()

Without:
