Thanks for the suggestions everyone!

I'm not entirely sure ;). I'm typing latex, but as far as I can tell,
this doesn't exist anymore, and is a wrapper around pdftex?

Nope.

Yes, lots.

Possibly, but the compile time stays pretty much the same even after
I've made it several times.

And to follow the suggestion of a file everyone can try, I made a
quick file as follows (inline because Mail's attaching confuses me at
the moment...) :
--------
\documentclass{article}

\title{Test Document}
\author{Dave Murray-Rust}
\begin{document}

Lorem ipsum dolor ....
\end{document}
--------

Here's a log of me texing it:

sys     0m4.965s

FWIW, most of the time, approx 5 seconds, seems to be before the line
"entering extended mode" is printed, and then about another 3 seconds
before the "Babel..." line. It appears to be CPU bound, as well - PDF
tex takes up 95-100% cpu for most of the run. Mind you, now that I'm
looking at it, top is taking 8% of my cpu, which seems a little
excessive.

For comparison, on my linux box it takes 0.150s to latex this file.

Thanks for the help!
Dave
