我有以下python代码:
import libtorrent as lt
import time
ses = lt.session()
ses.listen_on(6881, 6891)
params = {
'save_path': '/home/downloads/',
'storage_mode': lt.storage_mode_t(2),
'paused': False,
'auto_managed': True,
'duplicate_is_error': True}
link = "magnet:?xt=urn:btih:4MR6HU7SIHXAXQQFXFJTNLTYSREDR5EI&tr=http://tracker.vodo.net:6970/announce"
handle = lt.add_magnet_uri(ses, link, params)
ses.start_dht()
print 'downloading metadata...'
while (not handle.has_metadata()):
time.sleep(1)
print 'got metadata, starting torrent download...'
while (handle.status().state != lt.torrent_status.seeding):
s = handle.status()
state_str = ['queued', 'checking', 'downloading metadata', \
'downloading', 'finished', 'seeding', 'allocating']
print '%.2f%% complete (down: %.1f kb/s up: %.1f kB/s peers: %d) %s %.3' % \
(s.progress * 100, s.download_rate / 1000, s.upload_rate / 1000, \
s.num_peers, state_str[s.state], s.total_download/1000000)
time.sleep(5)
这似乎工作正常,但随后减慢到不到一个字节/秒:
$ python test.py
downloading metadata...
got metadata, starting torrent download...
0.00% complete (down: 195.0 kb/s up: 8.0 kB/s peers: 28) checking 3.069
0.00% complete (down: 133.0 kb/s up: 5.0 kB/s peers: 28) checking 3.342
0.00% complete (down: 29.0 kb/s up: 1.0 kB/s peers: 28) checking 3.359
0.00% complete (down: 5.0 kb/s up: 0.0 kB/s peers: 28) checking 3.398
0.00% complete (down: 4.0 kb/s up: 0.0 kB/s peers: 28) checking 3.401
0.00% complete (down: 0.0 kb/s up: 0.0 kB/s peers: 28) checking 3.405
0.00% complete (down: 0.0 kb/s up: 0.0 kB/s peers: 28) checking 3.408
0.00% complete (down: 0.0 kb/s up: 0.0 kB/s peers: 28) checking 3.412
它变慢了,永远不会完成。知道为什么会这样吗?
