Are you talking about the mitigation as described in this article http://johoe.mooo.com/trezor-power-analysis/ ?

Yes that is what I was talking about.

Hm, I bought my trezor just a few months ago, ... I think it's responsive enough, but I have no reference.
how much faster were earlier models exactly?

It wasnt having to do with earlier models. My trezor seemed to slow down significantly after the firmware update that came right after the discovery of that attack vector. But now it's seems to be back to the way it used to be. Also I could have just been experiencing an unlucky series of server problems with mytrezor.com around that time. Not sure.
