      $dirsync->nocache( 1 );

    If enabled, it will significantly degrade the performance of the
    mirroring process. The default is 0 - assume that rebuild() has already
    rebuilt the source cache.

  gentle( [ <percent> [, <ops> ] ] )

    Specify gentleness for all disk operations. This is useful for those
    servers with very busy disk drives and you need to slow down the sync
    process in order to allow other processes the io slices they demand. The
    <percent> is the realtime percentage of time you wish to be sleeping
    instead of doing anything on the hard drive, i.e., a low value (1) will
    spend most of the time working and a high value (99) will spend most of
    the time sleeping. The <ops> is the number of disk operations you wish
    to perform in between each sleep interval.
