Reported Latency

Just finally tried ASIO4ALL instead of my normal Focusrite drivers and WOO HOO!!  MUCH better performance.  Only issue is that Sonar's audio dialog reports a different latency than the ASIO4ALL control panel.  I'm only concerned that delay compensation is getting the right time, if Sonar has the right number than I guess I don't care if they are different.  Ideas?

FWIW, You're likely seeing "much better performance' because ASIO4ALL is using a larger buffer.
Thus, the latency discrepancy you mention.
IOW, You could achieve the same performance (or better) by running the stock driver at the same resultant latency (buffer size).
 
ASIO4ALL wraps a unit's WDM driver to appear as an ASIO driver.
There's no way it's more efficient than a native (well-written) ASIO driver.

Firstly, my experiment with ASIO4ALL was recommended by the fine gentlemen over at PCAL with the statement "....we've been able to achieve really low latency with it" Second: You may enjoy this read: http://www.staudio.de/kb/.glish/drivers/index.html

 

Thanks for the suggested reading, but I've worked with a DAW or two over the past 15+ years.
 
ASIO4ALL can achieve lower latency than running the stock WDM/MME drivers (for audio interfaces that don't provide a native ASIO driver). 
 
In the case of a unit with a poorly written ASIO driver, ASIO4ALL wrapping the WDM driver may provide better overall performance than the "crap" ASIO driver. 
 
When dealing with a unit that has a well-written native ASIO driver (ie: RME units), using ASIO4ALL will not outperform the native ASIO driver (when you compare equal round-trip latency).
 
FWIW, This is not the first time this subject has come up.  It's been brought up many different times.
Same conclusion each time...
