Almost every operation on my new Win 7 machine has been quicker than any other Win OS, yeah! But our new Line of Business app, which is in development, that uses ClickOnce for deployment, downloads the data incredibly slow. Current size is about 40 MBs, Seems to do a smart download and only download assemblies that changed, but then when it downloads that stuff the rate is probably around 1 MB/s.
The 1MB/s speed is significantly slower. So where does the problem lie? Installing from a Share on the LAN.
