Depends on the job, but I would think for most people on HN 3mbps would be considered painfully slow, which it is.

But even for the less technically apt, consider other common tasks that require speedy broadband. Something like restoring a 100GB iCloud backup to a new iPhone on a 3mbps connection would take over 3 days, assuming the connection (or your patience) could hold that long.

And you certainly won't be streaming your favorite shows in 4k.

If your dealing with larger files, you need a vm somewhere you can access remotely; instead of pulling the files down completely.
