says:
2.5 old (with offscreen buffers) 10.708
2.5 new                           4.378
2.4                               2.098

His first message 
(http://www.geocrawler.com/lists/3/SourceForge/9276/25/9237029/)
listed 13.586 for old 2.5 code.

So you are right, old code was not 1000% slowdown, only 500%. But main
problem is not speed of old code, but speed of new code. And if numbers
are right, new code is still 100% slower than 2.4.x code was.
