High Performance WIFI mode?

[Churten]

I noticed this in the what's new for the latest version and in the prefs, but can't find any indication as to what it actually does.

i saw this option too but would be good if the devs could chime in with more details on what this does.

I too would like an explanation of what this does.

I suspect this just enables high performance mode on WiFi which uses more battery but gets better speeds. The HTC one x has this option at least.

Having root access to an XPERIA X10i, it would be nice to know a bit more about "High Performance WiFi mode" as I may be able to 'tweek' the firmware/config on my phone to better use it if I knew what it was attempting to do.
