Actually, the FUSE overhead is extremely low. I've actually measured it using tools like bonnie++ using a home-made FUSE filesystem that effectively mirrors the underlying filesystem (i.e., just a passthrough), and the overhead was only like 5% compared to direct EXT2/3 access. -derek -- Derek Atkins, SB '93 MIT EE, SM '95 MIT Media Laboratory Member, MIT Student Information Processing Board (SIPB) URL: http://web.mit.edu/warlord/ PP-ASEL-IA N1NWH [EMAIL PROTECTED] PGP key available _______________________________________________ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/
