A survey on the countries' prevailing internet speed has revealed internet speed in Australia and New Zealand ranks among the slowest in the world.

The survey was based on 27 million downloads by 20 million computers in 224 countries from January to June 2011.

The survey found that average worldwide download speed is 580KBps, but New Zealand's average download speed is 364KBps, just slightly ahead of Australia at 348KBps.

Among countries with fastest internet speed, South Korea came in first with an average speed of 2,202KBps, followed by Romania (1,909KBps) and Bulgaria (1,611KBps).

Chief executive of Pando Networks Robert Levitan shares his insights about the results with New Zealand Herald.

"While, in general, developed economies outpaced the developing world in average download speeds, big names such as the U.S., UK, France, China and Canada were not even close to being the fastest... Instead, we saw high speeds in markets such as Eastern Europe where focus on infrastructural development and favorable geography promote a higher level of connectivity."
