I have eset file security (6.5.12017.0) on a 2012 server, and McAfee Endpoint security (10.6) on a Windows 10 box. If I try to copy a one line text file from the client to the server it stalls for around 10 seconds. I can't see any massive CPU spikes on either client or server, procmon offers no help either. If I disable on-access scanning at either the server, or the client the copy is instantaneous. Copying from the server to the client is also instantaneous. Copying a larger file from client to server has the 10 second initial delay then copies at a usual rate.
If anyone can shed any light on what else I can try to track the issue down, I'd be most grateful. Also if you have a machine that you can test and reproduce the issue that would be helpful too.
Many thanks,
Matt
