gnometerminal is a CPU hog - can I cache fonts?

[Mike Harding]

I'm using gnome terminal to do some big builds, like 'build world' or
similar, and I notice that XFree86 can use up to 35% of the CPU.  WIth
xterm, this seems to never be more than 3-4%.  I assume that this is
because of the font rendering.  Is there anything I can do to enable
font caching?  Does X cache rendered fonts?  I haven't really touched
the defaults or played with this stuff before, and appreciate any
help.
