As far as the distro goes, the one caveat used to be making sure you had one with a recent enough glibc so you could take advantage of Priority Inheritance with the pthread mutexes and such. That's pretty much no longer an issue, but FC10 does ship glibc2.9 which has the advantage of using PROCESS_PRIVATE futexes by default, which should give you slightly better performance in some situations. -- Darren Hart IBM Linux Technology Center Real-Time Linux Team
