Hello All!

Attached is the first page of the "dbperformance.php" page on a 1and1.com server.

Note the following
  1. The desciriptions for MyISAM cache hit ratio and InnoDB cache hit ratio indicate the Cache ratio should be at least 90%
  2. The value for BDB data cache size indicate an Error.
How do these results affect performance and how can I either correct the results or improve performance?
