Silly question... 
What makes you think that what you are seeing isn't already as fast as

You are looking at an async client versus a synchronous client, right? 

Also... what do you mean when you say 'client recovers' ... 
How are you measuring that the client has recovered? 

Thx

The opinions expressed here are mine, while they may reflect a cognitive 
thought, that is purely accidental.
