Thanks for the stat - our environment supports throughputs >1Gbps on a single processor. Near linear scalability is expected with additional chips up to 256 CPU's.
I agree with your comments on IPv6 - it's already here - might as well embrace the horror.

Yes, plenty :) ftp.heanet.ie serves about 1 million requests, well over a terabyte of data per day and maintains an average of about 220Mbps for http. It's roughly 10 times less latent, and serves about 5 times more per second under 2.0 than 1.3, and I benchmarked that in the early 2.0 days. Performance under 2.x has improved since. If I could use sendfile (my hardware is still broken in IPv6) I'd see a much bigger increase in performance. 2.x knocks the socks off of 1.x. I've benchmarked many other transitions, and though the improvement is smaller for dynamic content I've never seen the numbers get worse. Of course this is all going from 1.x prefork to a 2.0 worker mpm. More importantly though; 2.x has IPv6 support. And whilst many people reading this mail may think IPv6 is an obscure requirement, many of us are in parts of internet where it's de facto. We couldn't even consider rolling out an app which didn't have reliable IPv6 support. Many people are finding themselves in such parts of the internet, at an increasing rate. As an asside; It's been my experience that most of industry doesn't rate application performance all that highly in evaluation criteria (mainly because buying beefier hardware is an easier solution). -- Colm MacCárthaigh Public Key: [EMAIL PROTECTED]
