Aaron asked on FB:
Does it now support faster than 100mb speeds? Only reason I stopped using it
Replicator uses Win32 ReadFile and WriteFile from Kernel32.dll. Plus, there's a call to check the free space on the destination file after every file is checked.
Public Const API_BUFSIZ = 2 ^ 16
This is a 64k block size. Considering the speed of today's hardware, try just upping this to the maximum Win32 will accept. If that's all good, then perhaps set the block size based on how quickly the copy callback is being called. The point of the callback is UI, anyway...
