According to this link [1], preempt kernel is slower than generic. Why are we building the kernel as preempt? Do we really need low latency?

Where I work, most of the time, they're all a "general-purpose computer", unless they do something really special

Yep, but the Ubuntu wiki says one should use the generic kernel unless there are reasons to do otherwise.

There you go. My N900 records videos with stuttering as it is, even with a PREEMPT, Thumb2 kernel. It sounds like a generic one would make it even worse.

Yes, indeed, this makes sense
Maybe a lowlatency kernel could alleviate the issues with recording?
