is teracopy optimized for smb transfers?

Hey there I'm using teracopy on two clients going to one target over SMB and my speeds are about 80-95MB/s and I have two windows file explorer copying to the same source, client switch and server are all using 40Gbe nics. I'm wondering what types of speeds we should be expecting? it's high res video footage so a mix of small metadata files and large video files.

Is teracopy optimized for network transfers using SMB?
