Connection Pacing (3 posts)

I use Fetch's "Mirror Folder" to backup and copy large directory trees with many files. When I do this with a slow, older Linux system, I find that the transfer eventually aborts because the Linux system cannot open any more TCP connections, and netstat there will show over 180 connections in TIME_WAIT. It seems that Fetch (4.0.3 on MacOS 10.2.4) is just too fast in this case. I would like to have TCP Connection Pacing as an option, maybe in the form of an N per second maximum limit. Ideally this would be a per shortcut option, since I only need it on a few hosts, but an Obscure Option under Misc would be workable for me. Thanks.

That's a great suggestion -- thanks!
One way that I've seen host specific advanced options like this implemented so they're flexible yet not complexicating the basic UI is to have an editable list of the hosts/IP addresses (or even IP address ranges) that the option applies to, with a maximum rate for each. This approach has the mild benefit that once you have recorded this limit for a host, you don't need to recall it each time you make up a new shortcut for that host. It has the downside that the limit isn't recorded in the shortcut, especially if you share shortcuts between fetch installations.
