Data Usage high?

I recently found Win10 has the capability to provide a network data usage overview by application.
I was surprised to see DAX.exe had used 105GB over the last 30 days. SmartSDR used 14GB and Cat.exe used 740MB.

I'm not suggesting anything is wrong but I'd be curious to see if others have the same experience and usage. DAX.exe was the one that surprised me the most.

The only digi mode I've been using recently has been WSPR, all other operating CW and SSB.

Any thoughts or comments?

Sounds intuitively right. I have two panadapters open and just one DAX channel going right now. DAX is clocking along at 3.2 Mbps vs. 0.8 Mpbs for SSDR, at least per Windows' reporting. That uncompressed high quality audio does take a lot of bandwidth. Another reason not to use DAX to send audio via a wireless network path!
