[MacTUG] Using ARD to copy to multiple macs -- now super slow

[Donald Duff-McCracken]

Hi have 2 macs that are running ARD, and other than a few software updates nothing has changed (to them or the clience) since the September but when I copy files to more than one of my lab macs, the speed becomes unbearably slow (and failure usually happens).

For example a ½ gig file copies to one mac in about 10 seconds. Usually I could send a handful of machines and it would not be that much longer (certainly loads faster than doing them one at a time). Now when I send the file to just 2 macs, it takes minutes to even get part of the file copied. (I have been copying to two macs when I have been writing this and am only at 2%).

I have replicated this on 2 different servers running ARD.

While we have some switches being upgraded in our area, none of them have happened that should be effecting these computers.

I have not investigate this fully but just wanted to see if any other ARD users can replicate this?
