I'll chalk that one up to it being Friday.  
Thanks Bob.

I think you misread. The LR version is minutes, the service program is 
seconds.

Hi Alan,

What are you doing that you get worse performance from a service program 
than from a cycled program turning LR on?

This honestly makes no sense to me.  Is the service program running in an 
activation group that's constantly being reclaimed so the service program 
needs to 'reactivate' on every call?  That's the only situation I can see 
a service program performing worse, and I'd also suggest, in that case, to 
redesign how the service program is used.

I looked at my number again. More like 48% faster.  20 Million calls.

2.06 minutes using main.
3.06 minutes with LR off
3.17 minutes with LR On

Of course, service program

3.41 seconds

This is measuring call performance only.
