What this mean outside high speed trading and market advantage is hard to determine.

Korea’s internet users surfed at an average speed of 24.6 Mbps in the second quarter.

Korea is trailed by Hong Kong, Switzerland and Japan who each saw average speeds around 15 Mbps. The United States ranked 14th with an average connection speed of 11.4 Mbps, which is still way above the global average of 4.6 Mbps. To add a little perspective on what these speeds mean: At 10 Mbps it takes around 50 minutes to download a 2-hour movie in HD quality.
