Even though on Fri, Oct 31, 2003 at 01:01 Keith Mitchell realized that everything he says should be taken cum grano salis, he unhesitatingly continued with this missive:

I've seen this as a client has 2 G4s and an xrack in our rack space. All machines go through a Cisco 2948, that goes through a bride on an Etinc BWManager, to a 7120, then to the facility gigabit switch. Transfers between any of the Apple machines are blazingly fast. >From the FBSD machines in the rack to anywhere else speed is fast. But between the BSD and the Apples speed drops to the 10KB ranage at times. >From the outside world the transfers from the BSD machines are limited only by connectivity and I got 6Mb/sec transfers from some SW at AT&T to the local machines recently - as we are on a Level 3 backbone and it's fast. I've also heard via a 3rd party that a person we are associated with at Omneon Video Technologies [omneon.com] that they had the problem there. They reportedly got a patch from Apple on this, but this appears to be something which is not distributed. Last week I was at an SACD listening party given by an engineer friend of mine and they were all engineers, musicians, producers, etc., and all used Macs and ProTools. A well known CD mastering engineer asked me if I knew why is Mac to XP transfers were so slow. So this a problem - not widespread - and not occuring everywhere. It's just some machines at some times. Just throwing this out as it appears not be isolated but not a big enough problem that Apple addressed in a general patch/fix - IF what I was told that what Omneon experienced is true. > Anyone have any clues on this bizarre problem? No. But I'm going to see if I can trace down what I have heard, that may only be rumors.
