online table reorg with brspace

I am planning to reorg a 200 GB table online with brspace with our production system with the command below

brspace -f tbreorg -a reorg - t table name

How about using -e 4 or 6 option for degree of parallelism using in productuon ?

it takes very long time to reorg without -e 6 ( or 4) as i have tried in QA

The table is heavily used and canot do off line reorg.

Your reply will be appreciated

Thanks
