The percentage is computed after blocks. The AVAIL is cylinders completely unused and INUSE is cylinders at least partially used.
At 54% you should not panic. But since you have few cylinders that are completely free, CP is less likely able to build long strings of consecutive blocks. You might want to check the block paging numbers in your favorite performance tool. Rob -- Rob van der Heij rvdheij @ gmail.com Velocity Software, Inc
