# fsx usage:
# 
# -N numops: total # operations to do 
# -l flen: the upper bound on file size 
# -o oplen: the upper bound on operation size (64k default)
# -r readbdy: $psize would make reads page aligned (on i386)
# -t truncbdy: $psize would make truncates page aligned (on i386)
# -w writebdy: $psize would make writes page aligned (on i386)
# 
# -Z: O_DIRECT (use -R, -W, -r and -w too)
# -R: mapped read operations DISabled
# -W: mapped write operations DISabled
