{{Since updating to the latest percona release the InnoDB page cleaner log that reports that it is running slowly has included two spaces between the words not and be. }}

 

For example:

2019-06-03T16:03:59.929818Z 0 [Note] InnoDB: page_cleaner: 1000ms intended loop took 10325ms. The settings might not  be optimal. (flushed=120, during the time.)
