Certainly multiple scps would take lots of time due to initiating  
multiple ssh sessions.

However, you can transfer multiple files in scp command if they are  
going into a direcotry.  Then scp turns out faster at 3/4 the time of  
sftp!

#### SCP ####
[]: time scp -q devrat:dev/ContextFree/_darcs/patches/*.gz p-scp

real    0m18.606s
user    0m0.613s
sys     0m0.904s


#### SFTP ####
[]: time sftp devrat:dev/ContextFree/_darcs/patches/*.gz p-sftp > / 
dev/null
Connecting to devrat...

real    0m24.749s
user    0m0.868s
sys     0m1.303s

I ran this several times and these times are representative.  (For  
the curious, the test data set was 5.8 megabytes in 354 patches from  
a real darcs repo.)

Of course, I'm not sure I know the efficacy of doing this, since  
command lines are usually limited in length....
