The kernel's job, other than managing hardware, is mostly to stay out of the way while the application programs run. In most circumstances, the kernel spends next to no time running. There's only so far you can go with a 'hyper performance kernel' to make it actually faster.
You could do some interesting things with buffering and scheduling to make it more responsive I suppose.
It's not like everyone else set out to write 'low performance' kernels, anyway.

AOSS(1) General Commands Manual AOSS(1)
NAME
aoss - Wrapper script to facilitate use of the ALSA OSS compatibility library.
SYNOPSIS
aoss osscommand [arguments]
DESCRIPTION
aoss is a simple wrapper script which facilitates the use of the ALSA OSS compatibility library. It just sets the appropriate LD_PRELOAD
path and then runs the command.
This is useful in cases where routing settings (which can be made in your .asoundrc file) need to be applied to commands that use the OSS
API.
Examples of asoundrc configuration:
pcm.dsp0 { type plug slave.pcm "hw:0,0" }
or
pcm.dsp0 { type plug slave.pcm "dmix" }
In the above configuration examples, the pcm.dsp0 definition is used to wrap calls do /dev/dsp0. You can also wrap usage of /dev/dsp1,
/dev/dsp2, etc. by defining pcm.dsp1, pcm.dsp2, etc..
The PCM name to open can be given explicitly via ALSA_OSS_PCM_DEVICE environment variable, too. This overrides the default dsp0, etc.
Note on mmap: aoss mmap support might be buggy. Your results may vary when trying to use an application that uses mmap'ing to access the
OSS device files.
Arguments
osscommand
A command that uses the OSS API
arguments
The appropriate arguments and options for the OSS command.
AUTHORS
The OSS compatibility library is by Abramo Bagnara <abramo@alsa-project.org>. The aoss script and this document are by James Tappin
<james@xena.uklinux.net>.
