A patch for this (and other somewhat inefficent code, especially on a Geode with 300MHz ;-) ) was already sent to Klaus. It introduces a few hashlists in parallel to the channels and event structures. With an empty event list, the ARD transponder needs about 40% CPU (but the thread is also niced), after a while the load goes down to about 1% (both numbers on the Geode system). http://www.vdrportal.de/board/thread.php?postid=310366#post310366 But beware, it's only tested on 1.3.21 and contains some other experimental patches... -- Georg Acher, acher@xxxxxxxxx http://wwwbode.in.tum.de/~acher "Oh no, not again !"
