Since IE8 shipped last week, I've read two criticisms repeatedly: One is the burning question of whether IE8 is faster or slower than its competitors; the other is whether it makes reasonable use of system resources. In this post, I explain why some people are seeing performance issues (and share an obscure system tweak that might just cure IE8 performance and stability problems). I also take a closer look at why you might prefer a browser that uses more memory than others.
