Hi Amulya

First of all, please stop using QHttp. Use QNetworkAccessManager like the 
documentation asks you to.

Second, we need a better explanation to understand what you mean. I can reach 
11-12 MB/s downloads on our office network using QNAM (100 MBit/s full-duplex). 
That's the limit of the network.

Also note that the problem might be the measurement you made.
