What’s the best internet from PHIL to KOREA

My friend has a call center company here in Philippines and I work as an I.T. We applied leased lines because we believe it can solve our problems n terms on fast and reliable internet access. Now, when we test the speed going to KOREA because that’s our main site how come it shows only 50% speed of our plan availed, instead of 100. When we do speed test on www.speedtest.net it shows 99% which is okay. I don’t have any idea on this, im just new on this business.
