Thanks for the tip.

That seems like a better measurement of network latency.

Okay, but the same applies to the ILE interface that I use.

If you're using a network sniffer, you might be just getting an ATK error message, rather than actually testing the application.

I was measuring with Google Chrome, and Fiddler, and seeing actual results - if that makes a difference.

I understand that the comparison is rough.  I'm just trying to get a basic feel for how the ATK framework might be affecting performance - not to impune php.
