FP2: Recovery history file improvements might increase performance

The process of writing to the recovery history file in DB2® Version 10.1 Fix Pack 2 is now more efficient. This improvement might result in general speed increases, especially as the recovery history file size increases. These speed improvements occur automatically; no change to the system or queries are required.

Managing the size of the recovery history file is still an important part of maintaining performance. However, as a result of the improvement to the recovery history file, you might be able to reduce the amount of pruning that is required without affecting performance, especially on systems with many transactions.
