That article is way too hypey. It sounds like one of those strange american commercials you see sometimes at night, where two overenthusiastic persons are telling you how much that strange fruit juice machine has changed their lives, with making them loose 200 pounds in 6 days and improving their performance at beach volleyball a lot due to subneutronic antigravity manipulation. You usually can't watch those commercials for longer than 5 minutes. The same applies to that article, I couldn't even read it completely, it was just too much. And is it just me or did that article really take that long to mentioning what dtrace actually IS? Come on, it's profiling. As presented by that article, it is even more micro optimization than one would think. What with tweaking the disk I/O improvements and all... If my harddisk accesses were a microsecond more immediate or my filesystem giving a quantum more transfer rate, it would be nice, but I certainly wouldn't get enthusiastic and I bet nobody would even notice. Maybe, without that article, I would recognize it as a fine thing (and by "fine" I don't mean "the best thing since sliced bread"), but that piece of text was just too ridiculous to take anything serious. I sure hope that article is meant sarcastically. By the way, did I miss something or is profiling suddenly a new thing again? Regards, Julien
