But even without that, the window size still has a limit much smaller than TCP. Jukka, can you give the bandwidth and latency for the connection you're accessing over, and the speed you're expecting from it? (Just a latency estimate from 'ping' or whatever, from the client to a fileserver, if the network between the two machines allows it.) You mentioned a 100m/5m connection before, but not how big the delay is to a fileserver. -- Andrew Deason [email protected] _______________________________________________ OpenAFS-info mailing list [email protected] https://lists.openafs.org/mailman/listinfo/openafs-info
