How fast is iOS 6 beta 1 on iPhone 4?

[macbook pro i5]

Because I have an iPod touch 4 for testing and it crashes all the time so I don't want to use that,will the iPhone 4 not unexpectedly crash as much as the iPod touch 4?

 

[Major General]

I haven't had any crashes at all, things have ran smooth for me, apps load way much faster and certainly don't crash like they used to

Now has anyone else installed iOS 6 on an iPhone 4?
