lock manager and row security (JDE.INI)

I found a doc that said I could improve client side performance issues by adding the following entries to my client JDE.INI:

[LOCK MANAGER]
Server=EnterpriseServerName
RequestedService=NONE

[SECURITY]
Row Security = DEFAULT

My settings are currently:

[LOCK MANAGER]
Server=
RequestedService=NONE

[SECURITY]
Row Security = NO_DEFAULT

I have tested the new settings and found no improvements, or problems for that matter. Does anyone have an opinion on whether I should change? I am fighting some on going performance issues so any suggestions would be appreciated.

The document says that adding the server name prevents latency, and will NOT turn on locking. The Row Security setting is supposed to change where “WHERE” SQL clauses are executed (DEFAULT = server side; NO_DEFAULT = client side)

Thanks
