回复：连接数

节点达到 15 个连接后就不再尝试发起连接。如果你能接受传入连接，那么其他节点连接到你时，连接数可以远高于这个数；否则最多就是 15 个。
我不知道保持 15 个连接是否有任何理由。也许应该是 10 个。
由于现在只能向外连接的节点大多数时间都在 15 个或接近 15 个，你应该会趋于一个平衡值。45 表明，每 1 个接受传入连接的节点，对应 3 个只能向外连接的节点。
连接数以后不会再是衡量网络规模的好指标。应该有人定期在 chat.freenode.net 的 bitcoin 频道里进行 IRC 统计用户数。这会给出网络节点总数（TOR 节点除外）。
区块生成速度又超过预期了。大约 5 天后下一次调整时，我们还会迎来一次难度大幅上升。

Nodes stop trying to initiate connections once they have 15. If you can accept incoming connections, then you can get well above that from nodes connecting to you, otherwise you max out at 15.
I don't know if there's any reason to have 15 connections. Maybe it should be 10.
Since nodes that can only connect out are probably at or near 15 most of the time now, you should level off to an equilibrium. 45 suggests a ratio of 3 out-only nodes to every 1 in-accepting node.
The number of connections won't be a good gauge of the size of the network any more. Someone should periodically IRC to the bitcoin channel on chat.freenode.net and count the number of users. That gives you the total count of network nodes (except TOR nodes).
Block generation is again running ahead of pace. We're in for another big step up in difficulty at the next adjustment in about 5 days.
