Hi Chris,
 
I guess you have not read my last email yet. I think of it as putting two  
32-bit pieces of info on a 64-bit data bus whereas for two 64-bit pieces of  
information it takes two fetches or twice as long on the same hardware.  
Depending upon the number of bytes for each data type for 32-bit versus 64-bit  
20% performance reduction makes sense.

As for compressing the pointers all I read is it improves response time  so that 
maybe running on 64-bit java the program is only 1% slower. I am  assuming the 
pointers are compressed after the first pass or even before the  byte code is 
run.
 
Regards,
-Tony
