On my machine (win-xp SP3) at work the Internet seem slow, every page takes > 20 seconds to load. So I tried to diagnose the problem. Here is what I did :
- Check the internet connection speed
- I went to speedtest.net. The test took a long time to start, but when it started went pretty fast. 12ms ping, 9.36 Mb/s download and 0.73 Mb/s upload. I did the same test on another computer on the network and got the same result, but the page loaded faster and the test started right away.
I tried this in differents browsers
I check the ping time to some server on the internet.
- ping yahoo.com. gives me times of less than 30ms (yahoo.com still takes more than 20 seconds to load on this computer while it takes less than 4 seconds for others machines on the network)
I thought it could be slow DNS resolving, but the addresses seems to be instantly resolved when I do pings
I disabled the AV, didn't change anything.
What should I test next? It seems I've eliminated every possible source of the problem I know.
