It's no surprise. My implementation runs almost twice as fast on my
2.13GHz Pentium M laptop than it does on my 3GHz Pentium IV desktop --
I guess this is due to the larger cache of the laptop.

What I noticed, though, was that your implementation did not gain any
speed from the desktop to the laptop -- something I can't explain.

I am also running Saxon (8.7) with the -3 option.

Are you using Saxon 8.7 or an earlier version?

To summarize, the results, unfortunately, vary greatly depending on
the computer they are run.

On my laptop my implementation has been faster in 5 out of 6 cases.

Anyway, the purpose of this thread is for any sudoku xslt
implementation to improve, which I already see is the case.
