64-bit DB2 v8.1 FP10, AIX 5.2.

I have ~100GB logs have to be rolled forward after a restore (~1TB database) to a 2-way p570e server. It seems the rollforward is quite slow (aroung 800KB/sec).

Is it possible to increase the number of "db2redow" process (there are two currently) to speed up my rollforward ? or is there any parameters could help my rollforward ? Thanks a lot....
