Yupper! If you're using a "public internet access" then the torrent client is probably being throttled by the IP provider.
The absolute two best torrent clients are Bit Torrent and uTorrent. Basically they're cookie cutters of each other, the uTorrent based on the Bit Torrent engine.
From Wikipedia:
µTorrent (or
uTorrent; commonly abbreviated as "
µT" or "
uT") is a
freeware,
closed source BitTorrent client by
BitTorrent, Inc.. It gets the "
µ" in its name from the
SI prefix "
micro-" meaning "one-millionth", referring to the program's small
memory footprint: the program is designed to use minimal computer resources while offering functionality comparable to larger BitTorrent clients such as
Vuze or
BitComet.
The program has received consistently good reviews for its feature set, performance, stability, and support for older hardware and versions of Windows. A report showed that µTorrent is the second most popular BitTorrent client (after the Chinese
Xunlei).
[11]
It is available for
Microsoft Windows and
Mac OS X. A
µTorrent Server is available for
Linux. All versions are written in
C++.
[12]
The program has been in active development since its first release in 2005. Although originally developed by
Ludvig Strigeus, since December 7, 2006 the code is owned and maintained by BitTorrent, Inc.
[13] The code has also been employed by BitTorrent, Inc. as the basis for version 6.0 of the
BitTorrent client, a re-branded version of µTorrent.
