.gif" width=73 align=right vspace=5 border=0>I just ran my first scan with the improved Radio aggregator (not released yet) that knows about Weblogs.Com for RSS. I haven't added code yet to quantify the performance improvement but it feels quite substantial. Out of 119 feeds that I'm subscribed to, 28 are pinging weblogs.com, which means that I can find out if 28 of my feeds have updated with a single HTTP request. If they
all supported the new method, I would only read a feed when it changed, never to find out
if it changed. (Postscript: After putting in timing code, this optimization appears to have shaved about 30 percent off scanning time. Of course it matters how many of the optimized feeds updated, so there's no precision to that number. Also, after this scan, 30 of my feeds now support the feature. Heh.) [
