Thank you for the advice, I appreciate your help!
I did some more testing this morning and here is what I found:
1. Yesterday I was *not* using the same font (lucidatypewriter) for
gnome-terminal that I used for the others. I must have left the "use
the system terminal font" setting on by accident. I am sorry about the
When I actually use lucidatypewriter I get 70 seconds instead of 300.
2. Even when using the system terminal font setting I am able to get
the 70s result by disabling antialiasing using your suggested .fonts.conf setting.
3. GDK_USE_XFT=0 doesn't seem to make a difference with the version of
gnome-terminal (2.4.2) and GTK (2.2.4) I have available. It doesn't
affect performance and it doesn't turn off antialiasing - I verified
that with xmag :)
70 seconds, while still a bit slower than the others (and a lot slower
than rxvt), is definitely major improvement over 300!
I will stop using GDK_USE_XFT=0 and learn about fontconfig.
