I think if these tests were redone with optimized settings in Opera, it would show Opera slightly ahead of Chrome. For example, on page load, Opera is set to draw in one second intervals during load, by default. Obviously for simple sites that load under a second, Opera will preform poorly. Another example is memory usage. They called Opera memory hungry but that is ridiculous. Opera allows you to set the maximum memory limit and is capable of caching to memory. Any unused memory is allocated to cache. You can greatly adjust Opera's memory usage by disabling page caching (set to 1000 by default), lowering maximum memory usage, removing history (set to 5000 pages by default), removing tab thumbnails; however, while Opera's caching may hurt memory usage, it is amazing in the long run. The equvilent to having a local proxy in your browser. Anyways, the bottom line is Opera's default settings are NOT optimal and modifying securtiy, history, memory, caching, DNS prefetching, and the UI can improve its overall preformance. I cannot say the same for chrome where the only optimizations that can be made is DNS prefetching and some security stuff.
