Which Loads Faster tells you, well, you know
Have you ever wanted to compare how fast one site loads against another one? Instead of futzing around with multiple browser windows or a stopwatch, just head over to Which Loads Faster, and load the URLs into the split window interface. When you hit the GO button, it will load both sites in side-by-side frames, then make a judgment.
Keep in mind, there are a lot of variables at play, and you'll want to run the same test multiple times to get a better idea of what the average load speed is. Also, it's not clear whether the site automatically clears your cache, so you're going to want to do it manually between tests.
Of course, since each test will likely be different, it can help you create smart-ass screenshots like the header image on this post. Hey, we're just havin' fun here, right Lifehacker?
