When copying multiple (>100) files from my Windows 7 x64 machine to a remote system the copy action becomes really slow when it needs to overwrite files. If I copy to an empty folder it is as fast as I would expect, but when copying to a folder and overwrting it becomes very slow. For example 300 files (about 4MB) takes then almost half an hour.
I already tried already the following:
- Disable Remote Differential Compression
- disabled the automatic adjustment for the TCP window size (netsh interface tcp set global autotuninglevel=disabled)
- Use TeraCopy
But it doesn't solve the problem. It is still very slow when overwriting files. The same action on a XP-machine takes only about 30 seconds to complete.
