I am also testing internal ISP network and home LAN and wireless network and wondered if TestMy offers something for this. I can test ISP network but through SpeedTest.net which is limited in functionality. Same with home LAN and wireless network. In these both cases I have limited amount of data to test against with SpeedTest.net.
Interesting. I had 5 test runs of 200MB each from UK to Israel and speed almost matched if not actually matched what my ISP offers. However after I did same with US Dallas server, the speed dropped 3-5 fold. Something with peering or under-surface sea mediterranian cable leading to US? I wonder how that would be with other ISP... Maybe I can compare it with other local users who did same?
