Hi all.
Today I downloaded a torrent about 8 gigabytes in size. My tariff speed is 25000 kb / s during the day and I downloaded at a speed of about 3 megabytes per second. Then I needed to slow down the torrent client so that the browser would work normally on the neighboring computer, and I cut the speed to ~ 1.5 MB per second. To my surprise, on the contrary, the speed immediately crept up:

Full size
It was not a one-time speed jump, it remained at this level until the end and it got really faster.
Questions:
1. What is the reason for this?
2. How to fix and use this phenomenon?
Technical details:
OS: oracle linux 6u2 Torrent
client: Vuze 4.6.0.4
I am behind a WL-500 router with firmware from Oleg, real IPv6 addresses are distributed in my internal network (but I did not observe IPv6 peers during the jump).
It is now connected to the network via the ethernet2usb adapter left over from the mac book air. Built-in network card burned out exactly yesterday

Maybe it's still a torrent client bug? and he incorrectly calculates the speed.

As one of the assumptions, why the speed has not dropped - the restriction only affects traditional connections, after the restriction, uTP begins to be used more actively . I can’t check Vuze, but in uTorrent “apply restriction to uTP connections” is a separate setting that is disabled by default.
But going beyond the limits of the tariff does not explain this.

Is there a local network? Or just the Internet? If the first, then it is quite possible that the beginning of the download is not from the Internet, but from the local network.

Rather, temporary errors in the provider's software / hardware.
Or you have different speed limits inside and outside the local network. At least that's how it is with us.

But did it really flow at such a speed?
I have Internet at home from beeline at 30Mb / sec, but via FTP to one of the servers in Germany, the speed is consistently 2 times higher than the tariff plan.

Your ISP probably has a RETRACKER and is peering with another ISP whose subscriber is seeding the torrent you're downloading.
