Hi

My HW supplier doesn't sell 32-bit cpu's any more. That's the only reason 
why I switched to 64-bit.

Major problems were encountered to get things running again. Worst: 
plugins for browsers. Text to speech (mbrola) failed (I've yet to try a 
new binary available for AMD64). Surprisingly other apps (like ecpp 
primality test) work well.

As for performance: 64-bit is definitely SLOWER for most apps including 
crm114. But it is difficult to compare. My old 32-bit system has a Pentium 
cpu running at 3 GHz and the new 64-bit dual core runs at 2 GHz. And my 
*.css file are now two times the default size (don't know how this affects 
speed).

But speed is not a factor for me: load average is close to 0.00 most of 
the time. And most other things like pulling backups are bottlenecked by 
LAN speed and disk IO.
