JournalDelay=0 registry setting doesn't work.

Hello everybody. Usually I work in test environment, and I want to reach final result (archived email) as soon as possible. As you probably know that EV provides some delay (by default: 5 minutes) between phase when message was marked to acrhive and archiving at all. Symantec provides a solution how to decrease this time to 0, for example (in case if you have some general issue, or don't want to wait 5 min in test environment). http://www.symantec.com/business/support/index?page=content&id=TECH61066

So, I create new registry entry on all EV servers, restarted services\archiving task, but looks like EV doesnt' see JournalDelay registry key.

EV: 9.0.2

Exchange: 2010SP3.

Sure, emails are archived from Journal Mailbox as usually, with 5 min delay.
