Also, for me, what is interesting is not exact numbers, but rather a
general concept of how big the difference is between kernels.
Publishing a table of results will also make it possible to know what to
expect from let's say a certain intel atom processor run on a list of
kernels from an example repository.
I gather this could be helpful to the user when choosing hardware and
distro to a project, if the project involves as earlier mentioned one of:
* live audio processing
* monitoring
* using firewire devices
From a practical point of view for someone as ignorant about the
technical details as myself, I suppose I'm just trying to get a general
idea of what you get from different kernels.
So, I was making outlines on how to do these two things:
1. a test/script for making tests on a single machine to compare
performance on different kernels.
2. results summed up in a table that gives you a general idea of what
you get with different kernels.
There could perhaps be a number of different tables for different
processors, assuming that the processor is the main important factor
that decides the actual latency you get with a kernel.
These tests could then be published in a wiki, if deemed worthy.
- Why such a table should be made, and for who?:
Some practical uses that may require a rt kernel:
* live audio processing (requires low latency)
* monitoring (requires low latency)
* using firewire devices (As far as I understand ffado works best with
-rt kernels)
Possible/impossible?
