Probably common knowledge, but I just slapped together a quick test script to determine what kind of overhead there is between a) writing a function inline, b) keeping the function as part of an object (say, utility.isObject), and c) same as b, but get a reference to the function first. Each approach was iterated a total of 100,000,000 times to get usable time values. Tests were performed in Chrome 7, so YMMV. (more…)

PHP hashing performance experiment
Sunday, April 25th, 2010Today, in the never-ending quest to tweak server performance by a few milliseconds, I decided to do a bit of testing of various php hashing methods. I therefore wrote a quick script under php (5.2.11 currently, I need to update), which ran each test case 10,000 times to achieve a decent min/avg/max for each case, on strings of 10KB, 100KB, and 1,000KB in size.
