Fiber Internet Connections have redefined the end user experience, at the least, mine and my family's.
While the huge increase in speed from these fiber internet connections do not attributes to equivalent improvements in normal internet usages such as web browsing and emailing, it certainly does in other internet usages such as torrenting, streaming, remote access (to system or home surveillance), and downloads.
It is not uncommon to encounter the experience of false impression that the high speed fiber internet connection isn't capitalized by usage. Below is an example of the experience I had and why it is expectable.
Torrents of video files in the size of 300-400MB takes approximately 2mins to complete download for a 100mbps fiber connection. The throughput climbs up to 6.xMB/s as shown in the torrent client GUI before the torrent download completes. Well, this does not mean that there is a problem with the fiber connection but a mere fact that certain usage still has underlying limitations in its technology. Torrenting is one of them. Torrent downloading takes time to grow in speed as the torrent client of yours connects to more seeds and peers, and also the upload speed those seeds and peers are capable of.
For torrents that are small in size (such as 300-400MB), it would only be able to climb up to that speed and download completes before it can climb higher. Try to download a larger and very popular torrent. I am sure those of you on fiber connection of RPSs who DO NOT cap or throttle traffic will be able to achieve much higher speed.
For those who upgraded from ADSL or Cable (lower plans) to Fiber 100Mbps or higher, and have not re-configure your torrent client, it's time to tune it to suit the fiber connection as well as unleash the real performance.
Just a rough guide: Setting total allowed connections in torrent client to 500 or 1000 may works well for those slow speed ADSL/Cable connections, but definitely insufficient for high speed Fiber connections.
PS: For those on Fiber connections with mainstream RSPs who throttles/shape traffic, no matter how much tuning of torrent client settings done, it is still capped at whatever the RSP has defined.
