Hi,
If I have a 30MB line what should my speedtest results look like and how is 30MB calculated?
Is it download + upload = 30MB?
Currently I get 28.68 Down and 9.70 up
The speed is measured independently down and up - so not added together.
A little info:
ADSL for example is an Asynchronous connection - which means your "down" and "up" speeds are not the same. Usually your max "up" speed in SA is around 1Mbps. Downloads on adsl2+ max at about 20Mbps down and 1Mbps up. VDSL in SA max at 40Mbps/2Mbps - but you have to be really close to the exchange (few hundred meters)
When you move to LTE (cellular type tech - so iow cellphones) you have different ratios as well.
I'm assuming it's a wireless/fixed type or Fibre connection? - You would have to look at the details of what you signed up for to determine what your Down/Up ratios should be. It could be a 30Mbps Down / 10Mbps Upload - so your speed looks correct. There are some overheads and other factors like end point to where you are testing to (Local/International etc) that influences it, but if yours is a "broadband" service then you are looking good.
Most decent fibre providers give you approx half up of your down speed - so for example 50Mbps/25Mbps. You do get 1:1 packages (same up and down speeds/synchronous) but they are a lot more expensive, and require a specific use case - for example two offices that share a lot of data between them that need the same speed either direction.
try openspeedtest.com or perhaps saix.net for some speedtests and see what differences you get by selecting different regions - note it's only a throughput test - there are many other factors that might influence your experience/perception of speed, also depending on what you use it for. (Online gaming, casual browsing, streaming, Voice etc)
Last thing to mention perhaps - all broadband links are measures in Mbps - "Megabits per second"- not MByte. So your 30Mbps broadband link will give you a theoretical download speed of 3.75MBytes per second. So downloading a 100MB (or in old slang "100 Meg") file will take approx 26.6 seconds. Sometimes people think a 30Mb link should give you 30MBytes per second...

Hope it helps..
