A quick update to my ongoing Windows 7 RC1 performance assessment: It’s faster than Beta 1. It’s not just faster on high-end Vista hardware in 64-bits. I installed the 32-bit version of RC1 on my 64-bit hardware: Fast! More importantly, I installed Win7 RC1 on my circa-2006 Dell Inspiron notebook with a 2.0GHz Core Duo and 2GB of RAM. Again, it was fast. Not as fast as XP, but noticeably faster than Win7 Beta 1. Vista runs only so-so on this particular piece of older hardware.
I have a Lenovo 2.0 GHz Core Duo that’s even slower than the Dell. I’ve had Vista on that machine both in beta and in the final version since it shipped. That’s my next Win7 victim.
