SSH compresssion als abhilfe gegen verzögerung ?

PuTTY offers two features that may be of use: "local echo" and "local line editing". Local line editing buffers everything and only sends it to the server after a line return. That can make the command line much easier to deal with, but it may also make using a text editor hell.

PuTTY also has some other options for enabling / disable certain things (Nagle's algorithm) that may affect perceived connection latency. As I see it, the OpenSSH client doesn't offer all the features that PuTTY does in this regard, and I don't know of a Linux alternative that compares.

Otherwise, womble has it right.
