Ann: Wangle VPN Confirmed up to Twice as Fast as OpenVPN by PwC, page-14

I've definitely been sceptical of the claims, but you can't argue with independent testing.

After downloading the new Android update yesterday, the speed was very slow and I thought what on earth have they done, because I was getting great results on the previous version. Then I changed the MTU from 1500 to 1300 and I think I changed the port back to the default which made a huge difference. Very happy with how it's working now. I'll email them about it.

Hopefully they can get it working perfectly straight out of the box when it's released in a few weeks time, as I can see Joe Public dismissing the app quite quickly if they can't see instant results without having to mess around with settings.
