I know this isn't your "anyone seen speedup" thread, but I'll drop my two cents
in here.

FYI, Curt, at work, where I run an identical build of xastir to the one at 
home, with a filtered firenet and aprs2 feed (filtering in a radius around
home, and also within 500KM of the center of Hurricane Ivan), loading 
terraserver and USRadar maps and a handful of tiger shapefiles and GNIS data I 
see Xastir hover around 2%, with spikes to 30% and up of CPU when reloading 
maps, dropping to below 1% if I turn off the feeds.  That's a 2GHz P4 machine 
running FreeBSD

At home, TNC only, no online maps, same shapefiles, no WX radar, xastir sticks 
to about 0.05% CPU on a 2.6GHz machine with the same OS.

On Windows 2000, on another 2GHz machine with 640MB ram, we're looking at 
80%-90% CPU usage with the only feed being the server port on the above home 
machine.  Spikes up to 90+% every time there's a packet received or an expose 
event, drops to around 82% and stays there when everything's quiet.  X doesn't 
eat that CPU when xastir is not running, but it's clearly related to xastir's 
use of X.
