Black VEXnet keys

Would it be fair to say the old VEXnet wifi adapters provide a higher throughput than 2.0 adapters? Our teams noted a pretty drastic slowdown with downloading and more lag during debug when we moved to 2.0 adapters. Wondering if in a quiet wifi environment there would actually be a benefit to using the old ones during development/testing?

I have not benchmarked any of this in a long time so this information may be out of date now, however…

Vexnet 2.0 was faster to send data to the cortex than Vexnet 1.0 by about 20%.
Vexnet 2.0 was slower to receive data (ie. debugging) from the cortex than Vexnet 1.0, almost half the speed.

VexNET 2.0 data rate study

but that was two years ago, the actual rate may have been tweaked since then.

For most debugging I try and use a USB cable between joystick and cortex, obviously not always practical. Close any unneeded debug windows in ROBOTC, that will stop ROBOTC polling for that information and speed up the update rate in other windows.
