I'll echo the 3.x vs. 4.x observation. > Sometimes I wonder if Linux puts more of a buffer on DVDs than > FreeBSD does, given the way that most of the linux DVD programs > are written (read, decode, display, continue) they tend to IO > starve themselves under FreeBSD. Double buffering the I/O is a definite win. This is really an application space issue, since you want to buffer at least two key frames and the associated deltas... Linux tends to do this automatically. I've also noticed that Linux tends to precache the index data (just like the MACH paper that cached the entire FAT for an MSDOSFS and turned off UFS cacheing as "unfair", in order to "prove" that MSDOSFS was "faster" than UFS), which may be a good idea, or at least a useful mount option. Also, look at the optimization options chosen by configure in Linux vs. FreeBSD for compiling the player. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
