No, that is actually a very accurate statement. An algorithm will perform equally well regardless of the language chosen. How well the actual implementation performs overall is a separate issue. The performance or rather efficiency of an algorithm is usually expressed in the big-O notation, e.g. O(n), O(log(n)) etc. A linear search is O(n), a quick sort is O(nlog(n)) (on average) - both perform equally bad or equally well regardless of which language you choose to implement them in. > the same algorithm w/o external dependencies, such as db calls, or > calls to remote systems will run faster in java / c / c++ and others > than it will in php. An algorithm doesn't have external dependencies - but implementations might. /Per Jessen, Zürich -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
