Hi,
I have migrated from Spark 100 UFB plan to BigPipe a few months ago and I would not recommend anyone who's using P2P a lot (like torrents or P2P video) migrating to BigPipe.
While being with Spark I used to have a steady 10 MB/s on pretty much any popular torrents downloads, I'm hardy getting 6 on BigPipe now.
And it's not stable. Once it reaches 6MB, it jumps down to about 4 and then slowly grows back to 6.
I used to have no problem with watching P2P tv via Spark. Now, it's constantly freezing.
The support is only checking if you have a full speed on a speedtest.net to a nearest site and as it shows a speed about 100 Mbps they consider no issue found.
