I have measured 12 Mbit/s up and downstream. I have a wireless Network Adapter called Asus PCE-N53 (300Mbps 11n Dual band Wireless LAN PCI-E Card) and is connected to my local wireless router. I have Windows 7.

Facebook is very sluggish and load times for facebook are very bad, especially for images and video clips. Sometimes it just stops. Most other pages load very fast. What could be the cause of this? IPv6 timeouts or anything like that? I have tried flushing DNS cache, but the problem persists. Does anyone have a clue to what causes this issue? Cellphones on wifi do not seems to have this problem. Galaxy S4 and Iphone 4+.

ping and tracert for facebook.com gives:

C:\Windows\System32>ping www.facebook.com

Testing this page: Max connections test

Results in Page load time: 24266 ms in Chrome and a few broken pictures, while Page load time: 8740 ms in firefox with a lot of broken pictures.

I guess because they time out differently, or?

I have a quad-core intel i5 2500k with 16GB of RAM and a 250MB SSD.

    Can you post the traceroute to www.facebook.com and not facebook.com? Are you certain you are using IPv6 to connect to FB or IPv4? It would help to understand what your issues may be. – Paul Saab May 13 '15 at 4:26

    You are using the wrong hostname in your traceroute. Performance of facebook.com is irrelevant, because all you need to get from there is a redirection to www.facebook.com. – kasperd May 13 '15 at 12:00

    You have roundtrip times ranging from 43 milliseconds to 1 second. That's a pretty extreme amount of jitter. Your ping and traceroute commands got different IP addresses. But as far as I can tell, they are located close enough that you should be seeing similar roundtrip times. And since each of them displays significant jitter on their own, I conclude that the difference between ping and traceroute measurements is simply because the roundtrip time changed in the meantime. – kasperd May 14 '15 at 12:45

    You need to find out at which hop the jitter is introduced. A single traceroute command is not enough to identify that, so you either have to run traceroute many times or use a tool which can trace the connection periodically until it produce a clear picture. One such tool is mtr. – kasperd May 14 '15 at 12:47
