Some very interesting graphics posted in a ZDNet blog recently comparing the number of system calls made by Windows+IIS vs. Linux+Apache to serve a very simple web page. Short story: Everything you’ve ever heard about the fabulously complicated plate of accreted spaghetti code in Windows is true. Does all that added complexity increase the inherent vulnerability of Windows as a server OS? Probably. But getting to the real-world truth of that claim is nearly impossible without being a genius engineer intimately familiar with both code bases. I only know the images seem to confirm what I already believe. Computerworld aggregates blogged notes and observations on the frightening pics.
