Not 100% - see below > 2. Is there a way to compile mySQL on Linux so that it behaves like on Sun > where by there is the safe_mysqld and mysqld process only no matter the > activity? If so, how? MySQL behaves identically on Sun and Linux - that is it creates a new thread for every connection (not really, there's a cache for threads, and they can be reused, but it doesn't change the picture in general). ps in Solaris shows only one entry for mysqld - that's correct, there're only one process. In Linux, ps shows every _thread_ as a separate process - that's really misleading, as they are not different processes, they are different threads in the same process.
