Re: latest hiper group

Rob,

I'm not sure what you mean about not using 100% of the bandwidth. I download more PTFs than the average guy (currently 35GB of PTF images on line) and I routinely get downloads waay over T1 speeds, as high as 500 KB/s. Remember that a T1 is about zero.15% (.0015) of a GbE so even a heavily loaded network is going to find room for that itty bitty teeny little dribble of traffic. It's much more likely that your T1 is being used for other things like spam, web browsing, spam, email, spam, streaming audio, spam, vpn traffic, etc. Oh and did I mention spam?

I ALWAYS do these downloads in batch, it's the only way that makes sense at all. Even at 450 KB/s it takes 20 minutes for a full CD image. I have a routine that does the download and then emails me the ftp output log when completed so I can review it to make sure all went well.

It does take awhile - that's why I do it in batch. And if you are talking about comm resources IBM normally doesn't run the lan at it's full rated speed. Translation - even though you have a GB ethernet attached to a T1 IBM won't use 100% of that T1's bandwidth. It's normally only a small percentage. As far as other resources you should be able to do some tuning. And if that doesn't work, and it's still bogging down other processes - buy a newer machine.
