The article could be appropriately titled to reflect this wisdom: solve every problem in whichever language is your strong suit. It's not always Java, and arguing that Java is the one-size-fits-all would earn you few friends. For web services the importance of the language is diminishing with solutions such as cache, messaging queue, etc. I'd go on a limb to say getting your cache right is the most important web service optimization. All statements of the form "it's relatively faster to write programs in language Y than language Z" are incorrect because it disregards important parameters such as programmer experience with languages Y and Z, and whether or not it's a comparison between 2 different programmers. Also there are some performance gains that only pay off at Twitter or Facebook scale [1]. Sometimes shaving milliseconds costs time but rakes in little to no benefits.
