Connecting to remote system using Screen Sharing is VERY slow.

A connection from Yosemite (10.10.1) to a system running 10.6.8 takes over a minute every time.

A connection from Yosemite (10.10.1) to a system running 10.10.1 takes about half a minute the first time. After that, it's immediate for awhile, but there's some kind of timeout where it starts being slow to connect again. (24 hours, maybe?)

Steps to Reproduce:
1. Open the Screen Sharing app.
2. Connect to a server by hostname or IP address.

Expected Results:
The connection should happen within a second or two.

Actual Results:
The connection can take over a minute.

10.10.1 (14B25)

Other apps, like Screens on iOS, connect to these same systems immediately. It doesn't seem like a problem on the remote end.
