Real Time Kernel for or against (1 Viewer)

[Cajun Mike]

If you are dong any audio, midi , video you need real time. what are you running?

What do you mean by real time? What's the difference between a real time kernel and a regular one?

 

[Cajun Mike]

regular kernel scans roughly 250 times a second where as low latency scans at least 1000 times a second and I really don't know the scan rate on rt or real time. If you are doing any audio or video or scada (supervisory control and data acquisition) control you need it.

linux-image-2.6.22-14-rt is installed on my laptop. Keyword(letters?), '-rt'
I have deviated a bit on the repo list, but not much. Not sure if that kernel is in the default list or not.
Have a look/see in aptitude (or 'whateverpkgmgryouprefer') for '-rt'.

Honestly though, I have found the Ubuntu kernels to be incredibly bloated, it's the 'nature of the beast' to make it 'user friendly'.

Roll you own!

Your doing yourself a great disservice by NOT learning how to compile your own kernels.

Here's an outstanding how-to for compiling a generic kernel on Debian/Ubuntu:

It's Debian based, so you shouldn't notice much difference than Ubuntu.
