slow-connection

Trying to copy a few TBs betweek Solaris 10 u9 systems A single scp only seems to be able to transfer around 120MB/min, over a 1GB network. If I run multiple scp copies, each one will do 120MB/min, so it is not the network as far as I can see.

Any hints on how to tweak the Solaris settings to open a bigger pipe. Have the same problem with another piece of software that unfortunately does not seem to be able to be split into separate processes.

I just read the Linux scp command issue question and it reminded me that I regularily forget to specify the colon in the host part of a scp command, and thus copying a file locally instead of copying to a remote host, e.g. I do scp foo host instead of scp foo host: But I never use scp to copy… >>> More
