I recently switch from a Time Warner 10/Mbps cable connection to a Verizon 75/Mbps fiber optics connection (FIOS) and have noticed some interesting things speed-wise. I use a program called GrabIt to download items from newsgroups which basically just downloads multiple parts in parallel.
I've noticed that with my new FIOS connection when I have 50 files downloading in parallel my speed maxes out at around 10 megabyes per second, which is very fast and perfectly fine. But once it is downloading only one part the speed will drop to around 200 kilobytes per second, which is very very slow to say the least.
Previously with my cable connection the number of parts being downloaded never affected the rate at which the download was occurring. Any idea what might cause this?
