Glasnost: Test if your ISP is shaping your traffic
Results for your host (220-134-xx-xx.HINET-IP.hinet.net - 220.134.xx.xx):
Is your upload traffic rate limited?
There is no indication that your ISP rate limits your uploads.
However, some of the measurements were affected by noise, which limits Glasnost ability to detect rate limiting.

Details:

There is no indication that your ISP rate limits your BitTorrent uploads. In our tests, uploads using control flows achieved up to 1992 Kbps while uploads using BitTorrent achieved up to 2408 Kbps.

There is no indication that your ISP rate limits uploads on port 6881 or 57333. In our tests, uploads on port 6881 achieved up to 1992 Kbps while uploads on port 57333 achieved up to 2079 Kbps.

Is your download traffic rate limited?
The measurement data is too noisy to detect whether your ISP rate limits your download traffic. Re-running the test while ensuring that no other downloads or uploads are running in the background might fix this problem.
