Ways to make a Realignment run faster in DP in background job

Hello:

We have to Realign some characteristics sometimes and it takes a really long time (over 40 seconds per record). Sometimes we might have a couple thousand records to Realign and its a drain on the system and time consuming for the user. Are there any parameters that can be tweaked to make this run more efficiently and faster in the background? My BI person has compressed and indexed the database, but it only saved a couple seconds per record.

Should I ask the Basis team to help out? I'm not sure if this is their area of expertise or not.

Thanks!

Andrea
