Hello Everyone

Lately i have been stuck with an issue with InnoDB page_cleaner

InnoDB: page_cleaner: 1000ms intended loop took 8311ms. The settings might not be optimal. (flushed=0 and evicted=0, during the time.)
Here are my innodb setting

innodb_buffer_pool_instances=8
innodb_lru_scan_depth=1024
innodb_page_cleaners=4
So as usual i looked at all the resources available and many pointed to decrease the 'innodb_lru_scan_depth' from 1024 to 256.

Is there a way to fine tune the parameter by running test (like sysbench) to validate, also to reproduce the issue?

Best Regards
