昨晚我部署了bos，持续请求接口。一开始记录的get info，高度差是1~2。部署了两个测试环境，每个环境5个BP节点。其他参数没变。

环境1：测试过程中变成了3，早上来变成了7 - 8。
环境2：早上来变成了5 - 6。

并且没有恢复的趋势。不知道怎么恢复，再测试，高度差会不会继续能加。

记录有8小时时区差。

恢复一个块的高度差了。
可以大致讲下吗
是没有交易，高度差就不变，有了交易，高度差会恢复？

The difference between head and lib is likely to be affected by the net traffic and your nodeos overload under batch-pbft protocol. Let's say if you are making HTTP requests (e.g. get_chain_info) to your bp node at a very high frequency, the overall performance will drop down significantly for sure.
Moreover, if you could try to carry on your tests on a larger size of bp schedule (e.g. 21, the same with mainnet), the performance should be getting more stable.
