--- Comment #7 from Dan Kegel dank@kegel.com 2012-05-10 14:19:44 CDT --- Created attachment 40112 --> http://bugs.winehq.org/attachment.cgi?id=40112 Kludge global flag optimization patch
The attached kludge patch adds a global bNeedWrap flag sufficient to pass the test suite. With this and my previous patch, appending 1k lines at 40k now takes 14700 ms, only about 3x native.
It's not enough at 400k, though; that's still 88800 ms, 11x slower than native.
