Performance: CheckSafetyDetach consumes a lot of CPU time for little gain

Guest shared this bug 2 years ago
Solved

Please see the attached dotTrace screenshot.

Class: MyMechanicalConnectionBlockBase

Method: CheckSafetyDetach

Does it need to do this expensive check and this frequently?

Such a detach almost never happens.

This is a low hanging fruit to make especially multiplayer servers faster.

Hello Victor!

Would be great, if you could attach world file.

Thanks!

Reproduced the issue. Please find everything attached.

It was an approximately 60 seconds long profiling session in dotTrace.

Please note, that the slowdown is not because of putting pistons next to each other. The problem is specific to all motor stators (bases), regardless of their arrangement. I'm not sure how much pistons contribute, so added those as well.

Please ping me on Discord if you need any help in investigating this.

Thanks! I can remove the fix from my upcoming performance plugin then. Good!
