Hello, I don't know what the baseline for the claimed 10x improvement is. I hope there is an ATS webinar soon to explain it.
I did serious amounts of dedup on 6.1 servers. They are now at 6.3.4.2+ and I don't remember a big improvement from the upgrade. This url, http://www-01.ibm.com/support/docview.wss?uid=swg21452146 says that the big tables and indexes related to dedup are put in separate tablespaces. So I can guess that if you can commit the disk resources to separate them there could be a big improvement. Wanda used to have a sig line about i/o and it is still true. If the separation of tables and indexes accounts for the bulk of the 10x, I don't know how an upgrade from 6.3 will get the dedup performance improvement without some downtime and direct db2 manipulation of the tables and indexes.

Someone on this list said 6.3.4.200 made it worse for them.
