[Qt-interest] wget vs. QHttp download

[Jason H]

I wrote my own downloader before QNAM was available. I was able to hit network 
limits. When QNAM came out it had a bug that made is significantly slower, which 
has been fixed in 4.6 and later.

Guys,

Recently I have been trying to calculate the download speed for our network, so 
basically what I did was just use QHttp to download a file on the server and 
calculate the time it took to figure out the network speed. However, the speed 
estimates I got were rather off the track, which led me to try out wget. With 
wget, the speed estimates are pretty much on the spot. Does anyone know why such 
a difference exists? I understand that the network speed can go up and down and 
it could be what is happening in this case BUT I have tried this thing literally 
hundreds of times now and everytime its wget that gives a proper estimate. QHttp 
download for some reason is always "slower".

Going through wget source code doesn't provide any lead as to what "special" it 
is doing. Has anyone else seen this behavior? Any pointers are appreciated.
