The file /usr/share/man/man1/perlfunc.1.gz is from package perl-doc,
version 5.10.0-19 in Debian Lenny.

Those numbers look the same, so we're working with identical test data now.

Installed debxo 0.4 GNOME variant on jffs2.

Installed rxvt and perl-doc.  rxvt package version 1:2.6.4-14 

Started rxvt -fn 12x24, left it size 80x24, tested using this
file, results are:

4.818s, 4.494s, 4.490s.

Maximised rxvt.  Tested again, results are:

4.829s, 4.809s, 4.809s.

This was without xorg.conf creation or changes.

Yes, my tests over wireless yield 0.131s, 0.134s, 0.138s.  Tests to
/dev/null yield 0.047s.

Yes, something is wrong.  Have you another XO you can test?
