以下为Finalmix自己翻译！
FasterN9是一个改变系统内部设置文件，让你的手机工作起来更有效率的软件
对高级用户：是一个让你的N9运行效率更高的C程序组的mod，开发版本（不稳定）除了上述功能，还会更改手机的I/O调度。
你要卸载软件时，请到手机的“设置”里面卸载软件！
关于软件的安全性：
我和很多论坛网友都已经测试过了FasterN9。而且, 目前没有任何对稳定版本的BUG报告. 这意味着软件不会给手机带来什么不可逆转的大问题了, 但这并不代表软件没有BUG了. 请看"已知问题"和"声明"了解更多.
请注意，某些设备使用开发版本（不稳定），会导致MALF问题。这个问题应该不会发生在稳定版本上, 但也不保准.
如果你不会刷机，或者很在意手机中的数据，请不要下载并使用开发版本（不稳定）。
声明：
这个软件旨在希望能够对自己手机有帮助的情况下使用，但是，没有任何保障！如果你将程序用于特殊用途或者商业用途，更没有保障！
已知问题：
1.如果你第一次安装后没有重启手机，你的手机会没有任何系统声音（包括闹铃）
最终警告：
开发版本（不稳定）可能会导致手机数据损坏，不要下载并使用！
长篇更新履历：
fastern9 (1.1.7) 测试版（尝鲜）; urgency=low
* 增加Ocho的优先级，后台播放流畅问题解决
fastern9 (1.1.6) unstable; urgency=low
* 尽量修复上个版本稳定性上面的问题
* 增加rPlay的优先级，后台播放流畅问题解决
* 增加Nineshark的优先级，后台播放流畅问题解决
* 优化安装脚本，虽然降低了安装速度，但是更安全.
——fastern9 (1.1.5) unstable; urgency=low
* Disk cache tuning. Please uninstall "Drop cache" if you have it installed, otherwise there will be no gain as it erases the cache
* I/O prioritization of some processes to reduce latency. This will be applied only to phones running in "open mode"
* QuasarMX full and lite lag fix
* Improved network (TCP) performance
——fastern9 (1.1.4) unstable; urgency=low
* New Daemon which changes the settings when the phone is locked/unlocked
* Due to the mentioned daemon, combined performance and stability
* Reboot on installation is back and hopefully won't cause MALFs
——fastern9 (1.0.1) 稳定版（推荐）; urgency=low
* 增加虚拟键盘优先权, 让滑动输入流畅性大增. 而且部分修复了Harmattan自身的BUG749：Web address bar drops Swype text input after initialization when there is matching history suggestion, 但是这个BUG还是很烦人.

* Fixed cuteTube lagginess when playing in the background.
* Reduced lagginess caused by I/O by reducing to half the scheduler nr_requests.

* Reverting to the default I/O scheduler and tunning its settings.
——fastern9 (1.1.0) unstable; urgency=low

* Changed cpu.shares of the standby group back to 2. Should improve performance, not sure about stability.
——fastern9 (0.9.6) unstable; urgency=low
* This is almost the same as 0.9.5. Diferences are:

* Changed swappiness from default to 3. Should improve performance, not sure about stability.
——fastern9 (0.9.5) unstable; urgency=low
