My provider have guest torrents tracker (It very fast speed, because use guest connection, don't calculate internet traffic ), but this tracker have little information

.
I go to second tracker(not guest connection, calculate internet traffic).
I add torrents file from 2 different tracker and file from first tracker downloads context not with the guest connection.
second file downloads not a full speed.
I want run downloads 2 file at the same time
what is the solution can you offer?
if I run separately
speed on first torrent: 2.1MB/s (guest connection, and apply ip ban, don't calculate internet traffic)
speed on first torrent: 128kb/s (guest connection, and not apply ip ban, calculate internet traffic)
speed on second torrent: 128 kb/s
----
if I run at the same time
speed on first torrent: 60kb/s (and provider calculate my traffic)
speed on second torrent: 70 kb/s
