I also hope that performance problems will be solved
before we are
forced to not use putcs.

It will be :-) I need to one align the data. Second I
plan to implement the patch recently posted here.

Patch still showed about 100% slowdown against 2.4.x, if I interpreted
yesterday's table correctly. It is better than 1000% slowdown, but still...

I could believe a slow down of 2x but 1000 I don't think so.

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.
