Build time is increased by 6x after upgrading from `>=5.1.1` to `5.2.0+` about sphinx

I'm wondering if there are any additional configurations we could adjust to further improve the build time.

Been looking into this a bit for sphinx-needs: useblocks/sphinx-needs#967 (comment)

One thing is to set: smartquotes = False as that is a big time kill (although in the newest docutils release I added some improvements to this)

Also looking to eventually improve multi-processing performance: #11746

Happy to hear about more reports like this though!

What happens if you disable it?

toc_object_entries = False

Just tried disabling it by adding it to my conf.py.
Using latest sphinx version, it's working 👍
Thanks man!! @AA-Turner

Build time now is approx 4min 50sec (lot better then before)

However, It's taking a bit more time while reading sources with new versions (not sure after which one).

I'm wondering if there are any additional configurations we could adjust to further improve the build time.

With disabling the toc_object_entries flag for my project,

• Prior to version <6.0.0, the build time averaged around 2min 30 sec
• However, after version >=6.0.0, it increased ranging from 4min 50sec to 5min 50sec (approximately twice as before).

Any insights on potential configuration adjustments or optimizations would be greatly appreciated.

Appreciate the pointers, @chrisjsewell

I've taken a look at the other issues you mentioned, yet I'm still struggling to pinpoint what's causing such a drastic increase in build time with the latest versions. I've noticed a substantial slowdown with sphinx-build post version 6.0.0, with the build process now taking more than twice as long as it did previously.

This slowdown is concerning, as we'd like to leverage the latest features, but the performance hit is making it impractical. Any further insights will be really helpful.
