English

A few cases to tell apart:

1. Unlike traditional compression software, billion-context only does incremental compression, never whole-context (global) compression. So seeing it compress more often than a classic tool is normal.
2. In some cases it will still compress frequently: if a compression happens every three or five calls, the model is most likely reading huge amounts of logs, code, etc., which trips the incremental threshold. If you have many such scenarios, raising nudge (default 50k) to 80k–100k improves things noticeably.
3. If none of the above applies, it's probably a bug — report it at github.com/ranxianglei/billion-context/issues, with your log attached if possible. Usually resolved within the week.

区分几种情况：

1. 区别于传统压缩软件，billion-context 只做增量压缩不做全局压缩。所以看到的压缩比传统更频繁很正常。
2. 有一些情况下，还是会频繁压缩：如果三五个调用就压缩一次，大概率模型在疯狂读入日志、代码等，触发了增量阈值。如果有大量类似场景，建议调大 nudge（默认 5w），调大到 8w 到 10w 可以明显改善。
3. 如果以上都不是，那么可能是遇到了 bug，请到 github.com/ranxianglei/billion-context/issues 报告，最好带上日志，一般会周内解决。
