I will try google for benchmarks of libkse vs linuxthreads (as my production servers are running happily on 6.0-BETA5), cause I has been driven into by my colleagues developers to use linuxthreads for mysql (we have multiprocessor systems and they say that linuxthreads perform better on MP systems than original FreeBSD stuff) - I must admitt that I have zero knowledge about threading in FreeBSD :/ so I didn't have any objections at all. > MySQL 5.x hasn't even hit beta yet, you definitely don't want to be=20 > using it on a production system. :) MySQL 5.0.13 hit release candidate, see: http://www.mysql.com/news-and-events/news/article_959.html --=20 martin hudec * 421 907 303 393 * corwin@aeternal.net * http://www.aeternal.net "Nothing travels faster than the speed of light with the possible=20 exception of bad news, which obeys its own special laws."
