What steps will reproduce the problem?

2.When torrent from leecher to seed it announce to tracker. 
3.But after first time, many torrents wait for another interval (not my tracker

and this interval more and more.

it sounds like some of your torrents may be paused by the queuing mechanism. 
make sure you allow enough "active_limit" and "seeding_limit" in the settings.

Once you're confident your torrents aren't getting stopped, there's also a 
mechanism to avoid announcing too frequently. There are separate limits for how 
many torrents announce to different sources. there is one tracker announce 
limit, DHT announce limit, local peer discovery limit and so on. see the 
settings.

If none of these help, maybe you could provide some more information about the 
state your torrents are in and if there's any correlation between any 
particular state and not announcing.

I set active_limit = -1 , active_seeds = -1 , active_downloads = 100.

And I find another problem, most of all my downloading torrent connected to 1 
peer,
But the I use the same torrent with uTorrent to download, then uTorrent can 
connected to many peers(about 5 or 6), the same network and the same machine.

In addition I set connection per torrent to 50.

what about the global limit? it defaults to about 200 iirc.

I set half_open_limit = 5 and connections_limit = 100000.
