Details:

If you run the following command with octave-4.2.2 you get:


time octave-cli -f --norc --no-window-system --no-init-file --no-site-file
--eval help

real    0m0.404s
user    0m0.000s
sys     0m0.015s


With octave-4.4.0 you get:

time octave-cli -f --norc --no-window-system --no-init-file --no-site-file
--eval help

real    0m20.462s
user    0m0.000s
sys     0m0.015s


That means starting octave is about 50 times slower in octave-4.4.0 and a
startup time of 20 seconds is really significantly slower.
