Do you have slow SCP speeds? If so, try this

A colleague pointed me at this hint recently which in turn was a hint obtained from another website, that the author was unable to credit, due to him having lost the link.

Edit your /etc/sysctl.conf file and add the following text to the bottom:
net.ipv4.tcp_window_scaling = 1
net.ipv4.tcp_rmem = 4096 87380 16777216
net.ipv4.tcp_wmem = 4096 65535 16777216
net.ipv4.tcp_mem = 8388608 8388608 16777216
As to whether this is appropriate guidance any more, I don't know, but I thought I'd share it to make sure it doesn't get lost in the ether.
