I was doing some work tonight so I took an opportunity to do some benchmarking. I compared two Tegra 2 devices: the Xoom and the Droid X2. The Xoom is running a Tiamat Katana Kernel and slight debloating. The X2 runs Eclipse v1.3 with the mashup build.prop.
This is the two side by side.
This is the Xoom. It scored 7195.
This is the X2. It scored 4880.
I know this isnt a super scientific method or anything but I think it shows how much these devices are being held back by the locked bootloader.
Sent from my Eclipsed and ICS themed X2.
