Browser speed and reliabilty may be one factor that determines if someone either loves or hates the web.
Microsoft’s Internet Explorer has never been a great performer, well maybe IE version 6 was faster, but IE version 7 put on the brakes by adding many security checks that some experts say are poorly implemented. Now IE version 8 is lumbering onto the scene with more features and much fatter than previous versions.
Apparently this bloated version is intended to run on Vista, but it’s resource hungry footprint is sure to bog down even powerful dual core systems. IE 8 eats enormous amounts memory, gobbling 350-400Mb per serving and requires 150-200 concurrent execution threads and 6 servings of iexplore.exe discrete process instances.  To top it all off, Internet Explorer 8 is twice as demanding as Firefox.
