What a load of crap. Quite surprising to hear that sort of tripe come from a respected figure like Rasmus Lerdorf... but then, he did invent PHP.
First of all, requests/s per server is not a measure of performance, it's a measure of scalability. I can take the same system he's got, buy 9 other identical servers, and get 10 times the throughput. Does that mean they're higher performance? No, just higher scalability.
Secondly, scalability is not your problem. Getting people to give a shit about your site/product is your problem. Scalability is a hard problem later, but it is only worth really worrying about once it is a real problem.
He continues on by stating that PHP developers really need to think about performance for not only scalability reasons but for green reasons.
Sounds to me like he cares about performance because of scalability. That's retarded.
Upon second reading, I'm beginning to think that the writer failed to follow what was being said. I can't believe that someone like Rasmus Lerdorf would say something quite so daft, and the style of the article is erratic to say the least. So maybe it's just the writer who misinterpreted what RL said.
