I've just done a quick comparison of the speeds of various XSLT
processors for transforming .prot.xml to html. There is a marked
difference between the processors, and xsltproc which is the TPP
default is not the quickest.

Tests performed on Ubuntu 9.0x 64-bit on a DELL R600 Dual Xeon 5500
32GB RAM. All processors are installed from their Ubuntu packages.
Input document was a large 200Mb .prot.xml file resulting from OMSSA
search of the 72-run MaxQuant dataset downloaded from ProteomeCommons:

xsltproc - 1011.96s
xalan - 1206.95
saxon-xslt - 491.95s
saxonb-xslt - 132.19s

saxonb-xslt works for me as a direct replacement for xsltproc in the
$xsltproc definition in protxml2html.pl

I've not tried the commercial Saxon-SA / Saxon-EE from Saxonica.com,
but they are supposedly faster still.
