Hello, I am using a 15 inch rMBP running 10.8.2, and I am having an issue with websites loading incredibly slow (like over 1 min). It is not the download speed of my Internet because I am still getting good speeds there. On my network there are 4 total computers (2 Mac and 2 PC) but this one is the only one having issues. Does anyone know anything that could be causing this? I appreciate any help!
