Actually, Reiser4 will even be more efficent: first because of the FS itsel= f,=20 second because we could then use sys_reiser4. It's a syscall designed for=20 reading little amounts of data from little files, without opening a fd,=20 calling read() and closing it. "Casually", it was designed to read little metadata files which store=20 attributes. However I think that syscall could also be supported by other=20 FS's - at least it is possible. However a compile-time option is worth of=20 note. --=20 Paolo Giarrusso, aka Blaisorblade Linux registered user n. 292729 ------------------------------------------------------- This SF.Net email is sponsored by: IBM Linux Tutorials Free Linux tutorial presented by Daniel Robbins, President and CEO of GenToo technologies.
