He specified SMBv2 so I think you're on track with him being on a Win7 / WinSrv2008 box. 

There are a number of variables at play here though, one of which is who the provider's in-between the two locations 
are and the quality / number of peering points you'd have to cross. If the endpoints were already setup, I'd schedule a 
number of decently sized (big enough that it takes at least 5 - 10 minutes for scaling to do its thing) test transfers 
hourly or once every couple hours over the course of a week to get a baseline and understanding of how time of day 
traffic affects the transfer. If it's live traffic on the other hand, where a user is pulling up some massive file from 
the other office, you're likely better off looking into a WAN accelerator appliance.

Honestly, this depends on what OS you are using.  Anything prior to Win7 you are likely to suffer from the TCP stack.  
Add in anything weird like ICMP filtering, load balancers or something else that eats the packets you are going to see 
varying results.

Hello folks,

Does anyone know what's the average speed for windows file transferring
(SMB2) between Hong Kong and Johannesburg?
Any guide on how to calculate/estimate this?

Thanks.

Regards,
