super slow speeds from director

Hey Graeme,

	I'm open to any suggestions or theories at this point but I want to 
remind everyone that this problem is not constant.  This problem 
happened for the first time about 2 weeks ago and lasted for 2 days. All 
last week was perfectly normal. This time, it started on Monday and 
today it actually seems worse than Mon/Tues. All through the month of 
Jan and up until the 14th (ish) of Feb, no problems whatsoever.

	How do I do that?

>>From home (4 Mbps cable) I fetch the image at about  10 KB/s
>>From work (lots of Gbps) I fetch the image at about 282 KB/s

	Yep yep. Doesn't make sense.

Thanks,
Matthew
