It should be reasonable; I use coda over a 28.8 kb/s modem which has similar latency, or higher when loaded. The read cache works well, and I use 'cfs wd -age 30' to get write-behind caching. > Does SFTP create sufficiently large windows to allow good utilization of > the link? I doubt it, since that's 28800 bytes in RTT*capacity. I think it will do 8 * 1k out of the box, but it should be possible to tweak the constants up pretty easily. SFTP/RPC2 really needs to be implemented over TCP (separate connection for data, keeping a pool perhaps) or SCTP - the transport protocol parts of it are a bit creaky. Coda has some problems with very weak connectivity (remove files, remove directory they were in before reintegrating rm of files used to lose). But I suspect you won't run into that too much if you stay connected, or if you avoid 'rm -rf' while in write-disconnected mode. -- Greg Troxel <gdt_at_ir.bbn.com>Received on 2005-03-29 19:27:48
