If you're going to be dealing with files that large, then you're probably better off switching to all TCP, since you can also switch to larger block sizes. Try comparing the performance of copying files with 'tcp,rsize=32768,wsize=32768' to your current settings. _______________________________________________ autofs mailing list [email protected] http://linux.kernel.org/mailman/listinfo/autofs
