[libtorrent] Python, download speed limit for all torrent

My Raspberry can't handle download speeds higher than 300kbps. Here is
the client code I am using:

import libtorrent as lt
import time, os

torrent_path = '/home/torrent'

ses = lt.session()

ses.listen_on(6881, 6891)
session_settings = ses.settings()
session_settings.download_rate_limit = 300 * 1000
ses.set_settings(session_settings)

for file in os.listdir(torrent_path):
le_file = torrent_path + '/' + file
print le_file
e = lt.bdecode(open(le_file, 'rb').read())
info = lt.torrent_info(e)
h = ses.add_torrent(info, "/home/Downloads")

while (not h.is_seed()):
s = h.status()

state_str = ['queued', 'checking', 'downloading metadata', \
'downloading', 'finished', 'seeding',
'allocating', 'checking fastresume']

print '%.2f%% complete (down: %.1f kb/s up: %.1f kB/s
peers: %d) %s' % \
(s.progress * 100, s.download_rate / 1000,
s.upload_rate / 1000, \
s.num_peers, state_str[s.state])

time.sleep(1)

print 'end of while, moving to next torrent in folder'

My problem now is with the "download_rate_limit" setting. If I run the
script the first torrent downloads at the set rate, but the next ones
will ignore this setting, reaching 10 MB/s and overwhelming the disk.

Why is "session_settings.download_rate_limit = 300 * 1000" affecting
only the first torrent? I tried moving the "ses.set_settings" inside the
for loop and even deleting the "ses" object at the end of the while loop
and declaring a new one with every pass trough the for loop, but nothing
changed.

Any suggestions?

Kind regards,

Mircea

Try to disable UTP because it is not rate limited (anymore).

is your issue ocurring during the same run, or after restarting the program?

I'm just wondering if you're using save_resume_data when you shutdown,
otherwise if the torrent starts again and it can't find the previous
download_rate_limit setting for the torrent it will set the
download_rate_limit to unlimited
<https://github.com/arvidn/libtorrent/blob/c05e29c48e6cc4878eafa4f84d4c87d18feb6627/src/read_resume_data.cpp#L131>
.

As for new torrents, when creating the add_torrent_params object, I'd set
the download limit on it by reading the value previously set on the session.

I am testing on local network (tracker and client).

download_rate_limit = someNumber
local_download_rate_limit = someNumber
ignore_limits_on_local_network = False
rate_limit_utp = False

With this the download speed gets limited, but with the sum of
(download_rate_limit+local_download_rate_limit). If download_rate_limit
is set to 75kb and local_download_rate_limit is set to 50kb my torrent
will download with a max of 75+50 (125kbps).
