The tool (at least the screen snapshots) does look nice, but the author seems to belong to the CHR camp (see tip 2 cut and paste below). I would take the recommendations with a full shaker of salt (i.e. never take it!)

• Quote -- The data buffer hit ratio (DBHR) statistic represents the percent at which a requested data block is found in the buffer pool. The more DBHR approaches 100%, the more the likelihood that the requested data block resides in memory. This reduces the expensive disk I/O resulting in better application response time. It is recommended to keep DBHR above the 95%. If it falls below 95%, you may experience performance problem with excessive disk I/O.
