We are observing that there is a lot of delay to complete any read or write operations using MariaDB level 11.4, while on the same system 10.11 is working as smoothly as ever. We are unable to understand what are the additional actions being performed in 11.4 which are causing the performance degradation. Kindly let us know if there are any factors which can cause this kind of degradation.

Let me know what kind of diagnostics you would need to investigate this further.
