I thought it was a fluke so i ran the test with IE11 multiple times and its always almost 2x slower for TTFB than chrome, canari, or firefox. I’m using the same location for all tests. TTFB for IE11 ranges anywhere from 800ms to a little over 1 second. My TTFB score ends up being a ‘D’. The other browsers i get around 500ms and always get an ‘A’ for TTFB. I wouldn’t think the browser would affect TTFB. Any idea whats going on?
