I has a exe software. It is not a single file package, it contains a lot of files. when I installed this software in OSD, I found it would spend 15~20minutes to download files.
It was very strange. The software is only 600 mb size. the speed of downloading 6 GB OS image is also much faster than this software.
I know downloading multiple files is slower than downloading a single file, if their size are same.
But the downloading of multiple files in OSD is "really" very slow.
Why? Cause of BITS or RDC? How to fix it?
