Description

After switching to the latest release we see a much higher cpu load on our system. With version 10.4.9 we had an load around 3.5 on an 8core VM. Now 95% cpu usage and loads around 35.0 will happen.

Switching the typo3_src back to 10.4.9 solves the problem immediately.

Seems to be related to MySQL.

thanks for creating the issue. can you check if this change fixes the issue for you? https://review.typo3.org/c/Packages/TYPO3.CMS/+/66752

as the change is limited to 2 files and rather simple it should be easily applyable - also manually

Thanks for the support. Seems to be o.k. now.

But I had to fix it in 10.4.9 too, deleting the cache and then doing the core update. Otherwise the load exploded immediately after changing the symlink. I guess because of the cached TCA?

Yes, TCA is cached.
