Ubuntu 11.10的通用内核与所谓的RT内核之间有什么区别?
- 音频延迟是否取决于通用内核与RT内核?其中一些音频捕获似乎总是有几毫秒的延迟。
例如:其他发行版都有它们。

Choosing a Kernel for Your Use Case
These are some simple guidelines provided to help you understand which kernel, and in which order, you should test to fit your use case.
- If you do not require low latency for your system then please use the:
-generic kernel.
- If you need a low latency system (e.g. for recording audio) then please use the:
-preempt kernel as a first choice.
This reduces latency but doesn't sacrifice power saving features.
It is available only for 64 bit systems (also called amd64).
- If the -preempt kernel does not provide enough low latency for your needs
(or you have an 32 bit system) then you should try the:
-lowlatency kernel.
- If the -lowlatency kernel isn't enough then you should try the:
-rt kernel
- If the -rt kernel isn't enough stable for you then you should try the:
-realtime kernel
