Have a look at this little study we did.

Our setup:

5 x DSL lines in JHB office 5x DSL Lines in CT.
6 x M-WEB 9 gig packages
6 x Telkom 3 gig packages
1 x IS Uncapped Solution

We decided to test latency, we pinged a local server then an intl on. here are the results:

10.0.0.5 is Telkom ADSL
10.0.0.6 is Mweb ADSL
10.0.0.8 is IS ADSL


Microsoft Windows XP [Version 5.1.2600]

So as you can see M-Web and Telkom werent all then bad, however when we went onto the IS line the latency almost DOUBLED !!

Below is the response I received from IS:

Hi,

Response times of around 600ms - 700ms is the norm for the ADSL traffic because of the fact that it runs over a satellite connection to the US.

We do have some very intelligent in-line devices to cache and optimize TCP data so even though the response times appear higher, the actual page load times and overall feel of the service is very similar to that of SAIX.

I must admit, we have had some teething problems but as of late things have been very stable and response times have been constant. Besides the peering link, which is an ongoing legal issue, things should be quite good.

If you experience any specific problems, please do contact me so i can assist where possible.

Kind regards,

IS Network Support

Interesting.. your thoughts are welcome....
 
Very interesting. Latency on IS international ping is slow because they use their cheaper satellite connection rather than buying international fiber optic bandwidth.

A ping across any satellite connection will be slower than fixed line fibre-optic.
