We have network program, on shared SMB2.0 storage.
When avast is active, program loading speed (from network) is 51Mbps and this is constant.
Whit avast disabled, loading speed is ~930Mbps
Same behavior is whit tightVNC network transfer on files.
Avast have some ~50 Mbps limit and it is not processor/ram/ssd bottleneck.
This is for avast 17.2.2517
Is there a fix for this?
Not aware of a bottleneck in the client. Try disabling all shields except the file shield and see if the same issue persists.
