What I find interesting about these projects that Intel spawns for Linux (PowerTOP, LatencyTOP and couple of others) is that regardless of internal implementation they are very useful end user tools. Here at Sun we seem to be missing interest in creating such things. Which is a bit of a shame. They are ideal vehicles for disseminating DTrace knowledge and exposing neophytes to the raw power of DTrace. To be fair Greg's DTrace toolkit helps in that respect, but still it sets the bar pretty high for anybody who would like to use it. It is easy to poke fun at LatencyTOP, but asking the right question could sometimes be even more important than being able to deliver the answer. Just my 2c. Thanks, Roman. P.S. I was able to extend the battery time of my Linux laptop 1.5x using PowerTOP. Can the same thing be done with DTrace? Perhaps it can, but I don't think I can code it up. _______________________________________________ dtrace-discuss mailing list dtrace-discuss@opensolaris.org
