Indeed! The attached script 'prints' 6x1024 'x' characters, and on
GNU/LINUX KUBUNTU 8.04.02 it takes:

4 seconds with Emacs CVS LESS THAN OR EQUAL TO (<=) 20090129 15:30

2:15 minutes, i.e. 60x2+15=135 seconds with Emacs GREATER THAN OR EQUAL
TO (>=) 20090129 15:40!

To reproduce:

$ emacs -Q &

M-x compile
C-a C-k
./test_script-6KB.sh

see above...
