Status: with only 25 stations on screen (out of 1484), it's pegged at 100%
Back to basics: have you checked ground-level configuration? Menu >

have mine set at High (950 MHz), and I suspect most units will be stable
at that. This allows xastir to fully render the screen and drop back to
around 20% CPU usage in a reasonable time.
I find zoom level 256-512 (OR the menu's selection of 1024) more than
adequate for local coverage - 8192 encompasses the whole of NZ, and
across the Tasman to Aussie. That takes around 20 seconds to render
(mapnik in Map Chooser), so patience is the requisite virtue :) . I have
my locality as a Bookmark at zoom 400, which shows all of the local APRS
repeater's coverage, and a bit more. My (small) town shows well at zoom 40.
I run this 24/7 online (no RF), and concurrently use amule for a
file-share "collector" of rarities, at around 60-80% usage.
Hopefully helpfully ...
