Here is a bug fix if you are using windows for your version 4.0 server. Newer windows versions run IPV6 which in combination with firewalls (so far windows and norton firewall for me) , interfere with Apache web server and make your log on and mysql queries run very slow. You can search microsoft which publishes a way to turn off IPV6, or you can do it manually, though some people report it may turn itself back on unless you edit the registry or use the microsoft fixit links. Manually, at the network and sharing center you click change adapter settings, highlight local area connection, right click local area connection and select properies. Under local area properties you then unclick internet protocal version 6. After that your concerns about which browser to use and issues with performance will likely just go away. I am using the xampp 3.2 upgraded to version 4.0 on windows 7 pro 64 bit.
