Just a note on this thread, we got everything sorted out. There was a
little asymmetric routing going on, but the great folks at HGC was very
quick in helping us fix this.
We had some problem with HGC support at the Hutch before, but they are
great and fast now. At the other end in Johannesburg,

Any guide on how to calculate/estimate this?
Worst case would be that XP is involved, then you're going to be limited
by xmodem-like
Probably quite nasty delays as anything over a few milliseconds delays
really badly affects SMB
around 90 ms it's just about usable and above 120 ms forget it.
have a look at some of the WAN accelerator products esp Aryaka who'll be
able to set you up in minutes with no capital outlay..
It all depends on the air speed velocity of an unladen swallow, and
varies if it is African or Eurpoean.
In all seriousness, you need to know the speed and latency of the
link before that question can be answered.

Thanks guys.
We do have Riverbed Steelhead appliances at both end.
According to calculation, maximum throughput can be attained

According to calculation, maximum throughput can be attained is ~330KB/sec.
With the Riverbed cold transfer, we should get ~600KB/sec. But I can only
get ~250KB/sec with the Steelhead doing its stuff

Hey Luan,
Here is a good guide that will help you optimise your throughput. As for
knowing the average, it all depends on pipe size, network topology, end host
configurations to even conjure a guess.

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
