Hi Phil,
directories which don't exist are not critical in respect of

You are running TeX Live in three different environments.  Two of them
are fast, one is slow.  You are now investigating the config files.
Is it possible to confirm that they are identical on all these

I don't know why Windows is [sometimes] so slow.  A LaTeX file written
by a colleague could be compiled within 40 seconds.  Under CentOS
running in a virtual machine on top of Windows I needed only 8 seconds.
My colleague installed Linux in a virtual machine as well and could
compile his document within 8 seconds too.

Why is Windows so slow?  Many people claim that the file system is
the culprit.  On the other hand I wrote a LuaTeX program where speed
matters.  It reads a few files from the file system and creates a PDF
file.  There is absolutely no difference whether this file is
processed on Unix or Windows.  Admittedly, I optimised the program so
that it doesn't depend on too many external files and I pushed as much
as possible to the format file.  Maybe the Windows file system is the
bottle neck indeed, but I'm not sure.

Phil, in order to avoid too many rooms of freedom, could you confirm
that the config files on all your installations are identical?  IMO it
doesn't make sense to investigate further until you confirm that they
are identical.
