On that hardware, a .NET application should be able to serve about 200-400 requests per second. If you have only a few hundred users, I doubt you are seeing even 2 requests per second, so I think you have a lot of capacity on that box, even with SQL server running.

check out scp or rsync

|
Use rsync so that you can continue if the connection gets broken. And if something changes you can copy them much faster too!
Rsync works with SSH so your copy operation is secure. |
scp -r <directory> <username>@<targethost>:<targetdir> |
Well, quick answer would to take a look at the 'scp' manpage, or perhaps rsync - depending exactly on what you need to copy. If you had to, you could even do tar-over-ssh:
tar cvf - | ssh server tar xf - |
Log in to one machine
> $ scp -r /path/to/top/directory user@server:/path/to/copy |
As non-root user ideally:
scp -r src $host:$path
If you already some of the content on $host consider using rsync with ssh as a tunnel.

Most examples I've seen use a variant of the Command-Pattern for this.

The `__dict__` attribute of an instance class contains all the class's members:
