I've updated my XP machine to 6.0.24, so both are now running the same version of Calibre. For converting very large books, the 64-bit Win7 machine is still dramatically faster. Eg, for "The Barchester Chronicles", the conversion times are:

64-bit Windows 7: 3m 57s
32-bit Windows XP: 8m 57s

ie, the Win7 machine does the conversion 2.3x faster, despite having slower CPUs.
