Load Average is too high while sync

Hello everyone,

I currently have the problem that my Nextcloud server always pulls the CPU immeasurably when syncing. Load average of 300 CPU to handle the process is still low.

I have a second instance that is not subject to any other configuration and it does not have such problems.

As soon as the sync starts, several hundred apache2 processes are opened on the problematic instance and run with CPU loads of 90% per process.

Does anyone here have an idea for a solution?
Maybe you can limit the simultaneous sync…
I am looking forward to your answer
