It appears that scp transfers to a Linux machine (even a VM running on the Mac) are about twice the speed of scp's to the Mac. This is true of both openssh 5.1p1 (supplied by Apple) and 5.2p1 (built from macports). Note that I'm not talking about anything having to do with DNS lookup; these measurements are dominated by raw transfer rate. $ time /usr/bin/scp -r user at IP:directory /tmp MacOS: real 1m54.649s user 0m1.879s sys 0m1.680s Linux: real 1m8.447s user 0m0.400s sys 0m0.856s Is this a known issue? Is there any way around it? Slow SSH is really intolerable, since I use it for everything. Thanks in advance, -- Dave Abrahams BoostPro Computing http://www.boostpro.com
