In the Time magazine out last week, they describe a condition affecting one in 50 people - this condition causes an inability to recognize faces, and in extreme cases, people cannot recognize their own face in a mirror !
You don't have to go to Europe...you can come to Massachusetts or New Hampshire (the Granite state). Basically, the basements are carved out of solid granite which has radon trapped in it...old old houses have built up quite a bit of radioactivity because of the radon 'oozing' out of the granite underneath.
You forget that India/China are like New York City all over...planes carrying 600-700 would go full all the time once the airline industry takes off.

Perhaps you had it misconfigured ?
I would expect little DSL/cable links to take a while to download but the T1s should have done a much better job.
One question is whether those T1 machines were actually uploading anything to the others ?
There is a leech criteria - if a machine is downloading a lot but uploading very little (or cannot upload because no one can connect to it because it is firewalled), then it will be throttled waaaaaaay back.
That's why I suspect a configuration issue.
When the Tsunami videos were posted to BT, nothing worked expect BT links, and there were 1000s of peers up/downloading so everything ran great.
All major ISPs use policymaps on their 'edge' routers to groom user traffic as per their internal network QoS model.
What this means is that *all* incoming packets have their IP TOS field rewritten to predetermined values...low pri for home users, med pri for business DSL and VPN users etc.
Whether BitTorrent marks a packet as bulk or not will not matter, heck, for that matter, all users would mark ALL their traffic as high priority and then where would the ISPs be ?
Try long distance traffic tests and measure latency and traffic loss with various TOS field values...you will not notice any difference.
You know, I was speccing out AMD64s too...and I was planning on running AMD64 Gentoo on it too !
The power util was my main concern...till I found a nice page which showed the power consumption of various processors...an AMD64 3200+ runs at 45W idle, 90W peak. The Pentium-M runs ~ 35W peak power.
So, the different is only 55 Watts.
That's ~ 1 KWHr/day. 30 KWHrs/month.
At 12 cents/KWHr, that's 4$ more a month.
I don't like cable modem service, so I deliberately chose DSL. Of course, that means I need to get the POTS service...but, I've gotten my landline service down to 8.44$/month with the "metered" service package.
And I make those 8$ up by receiving unlimited calls on it (instead of using my cell phone airtime), so it's practically free.
This post is probably going to get buried in the deluge of flames and arguments going on here, but I have to say it.
I've recently noticed a trend in the Slashdot forums, rabid dog behaviour.
Disgruntled people jumping in to attack whatever they feel is too restrictive.
And its just not the forums, even the articles that our "esteemed editors" are approving seem to be of the same type - "Little fry vs big unyielding giant".
It's not always wrong to enforce unyielding rules.
I just got a 200 GB hard drive to throw into my ReplayTV, that'll give me 65 hours of high quality recording space.
It's not that I watch a lot of TV, it's just that I like to watch TV programmes on my own time...if I record a little extra, it comes in handy whenever i get the couch potato TV-watching bug.
And, do you know you can watch a 4 hour baseball game in under an hour !!! All that time they waste getting ready for a pitch ! i just hit the "skip 30 seconds button" and they still haven't thrown the pitch. Imagine a 3-2 walk...it takes like 5 minutes to get that torture over with !
Believe me, if you like sports, get a ReplayTV/Tivo...you'll know what i mean only once you've gotten it.
This is great for my Gallery of photos.
I won't post a link (it'll still get slashdotted!), but what it does is it mirrors a photo when the first user clicks on it, and then from then on, there is no load on my server running behind a DSL line.
This is perfect for mirroring my photos...it all gets handled automatically ! and it saves me a ton of bandwidth !
Would you like an invite ?
I had 36 invites sitting in 6 accounts that i created from my original 6 invites...I figured that everyone had gmail accounts...I used to post them on my blog...click on the link above.
It is "entirely possible" that the Linux machine is acting as a router, switching all your traffic in C code. Not to mention it is probably sending traffic up and down the PCI bus, once at ingress and once at egress. The lookup of the IP destination address is probably using a whole lot of memory bandwidth, and if it's at all like a regular router, it's probably doing a full IP header Sanity check (using the IP CRC), version number and TTL decrement. After the TTL decrement, you would need to recompute the CRC.
I would say the Linux machine is your bottleneck.
Unless you could somehow get it configured as an ethernet switch, rather than a Layer 3 router.
It was a little strange...I thought the webpage download was interrupted...I'd never seen an article page that short before !
I guess I got modded down to score 0 because of my very short reply.
Must be the new slashdot changes...someone file a bug !
Slashdot Mirror
Then use the non-silverlight version of the page - http://pastehtml.com/view/1acy1f2.html
Then use the non-silverlight link http://pastehtml.com/view/1acy1f2.html
I see her ! I am using the Non-silverlight page http://pastehtml.com/view/1acy1f2.html

It's from the site www.digg.com, which also has a slashdot-like effect on websites.

i call mine 'FBI'...that should keep people away.
Try the 64-bit version of POVRay and run the benchmark suite...compare the time with the 32-bit version of POVRay.
Wheels within wheels within wheels.
"American Intelligence" is an oxymoron.

This article's just funny !
