I am using PageSpeed to test my website (home page | ~0.6Mo) currently hosted on my computer (wampserver on windows) and PageSpeed indicates that my server response time is high (0.6s to 1.2s).
I tested the home page of some website I hosted on Hostinger.fr long time ago (I was a newbie back then and I had no idea how important response time was | ~2.6Mo for the home page), and PageSpeed found that the response time was cool (less than 0.4s I think).
I did every thing I could but nothing works, my response time keeps varying between 0.6s and 1.2s randomly. Could it be because of my Internet connectivity (420Ko/s at its peak) or because of my computer performance (3.1Ghz Pentium 4 | 2.5Go RAM)?
