Strong slowdown in the recent versions
Problem
Hello, I found a very strange behavior. Looks like the version of lib that is a year older works better than the current one...
Branch develop:
Branch main:
Also, latest tag has broken wheel in bunnymark example.
Hi 👋 Yeah, that seems weird. I'll give it a test to see if I can replicate the issue.
My friend and I tested the performance decline by version, here are the most significant changes:
| Commit | Max entities per 60 fps |
|---|---|
| Present | |
| 4b9bfbdb | 22000 |
| 42b6af0a | 30000 |
| cd6a0a44 | 32000 |
| Past | |
I've also run bunnymark on my M2 mac and it's true that the performance has declined. Hmm, it seems there's only changes in dependencies? I think we need to check profiling to identify the cause.

Hello, not right now. I'm thinking that there might be the other way to improve the performance. Maybe we can optimize the component data storage for memory alignment. Not sure how much it works until experiment.

These are not version numbers. The version number does not appear in the Github Mobile app, that's why I sent a message.

Yes, these are 1.3.7 and 1.3.8, but I do not advise to tie into versions, since we're testing specific commits. From the pov of go get, both can be specified via @.
