that really is the problem. fatter links only make sense if you can put enough data on the wire to overcome the bandwidth-delay product. NFS suffers in this respect just like AFS. also, if your filesystem protocol requires a lot of individual transactions to do something like enumerate a directory, round trip times really start to add up. so even without caching and just bulkstat, AFS can wind up being a winner in some cases. _______________________________________________ OpenAFS-info mailing list OpenAFS-info@openafs.org https://lists.openafs.org/mailman/listinfo/openafs-info
