speed of cacheing depends on terminal?

[dv1445@xxxxxxxxx]

Hello,

1.5.17 with header caching enabled.  I've got read_inc and write_inc set to 
1000.  Nevertheless, I've noticed that the process of evaluating the cache 
(when I switch into a big folder) is significantly slower when I use 
Terminal.app than if I use xterm/rxvt over Apple's X11.

This is puzzling, since I thought caching has nothing to do with the terminal 
choice.  Anybody know why this would be, and/or how I can do something about it?

FWIW: I built using the BerkeleyDB libraries, since the other choices refuse to 
work with OSX.  (Actually, I finally got mutt to build with gdb, but mutt 
behaved *really* weird with screen-drawing, so gdb is a no-go on OSX).

Thanks.
