Mac OS X 10.x (Darwin) ,

->If you have problems with performance under heavy load, try using the --skip-thread-priority option to mysqld. This runs all threads with the same priority. On Mac OS X, this gives better performance, at least until Apple fixes its thread scheduler.

->The connection times (wait_timeout, interactive_timeout and net_read_timeout) values are not honored.

->This is probably a signal handling problem in the thread library where the signal doesn't break a pending read and we hope that a future update to the thread libraries will fix this.

Our binary for Mac OS X is compiled on Darwin 6.3 with the following configure line:

CC=gcc CFLAGS="-O3 -fno-omit-frame-pointer" CXX=gcc \
CXXFLAGS="-O3 -fno-omit-frame-pointer -felide-constructors \
-fno-exceptions -fno-rtti" \
./configure --prefix=/usr/local/mysql \
--with-extra-charsets=complex --enable-thread-safe-client \
--enable-local-infile --disable-shared
