That someone would be me :-), and the main reason I was asking for this to
be done is for three reasons:

1) I am sick and tired of listening to non-linux os people (primarily mac
and win os, obviously) how their os is "still" superior in this realm as if
they are still living in the early 90's. What is even more frustrating is
that they can always point to a website or a "study" of some sorts which has
supposedly measured these and/or some kind of an accmopanying article (and
even if that article speaks in Linux's favor, they still manage to twist it
in some shape or form in order to suit to their purpose). You cannot believe
how strong this kind of propaganda is in the real world! In order to propel
the popularity of linux as a multimedia station of choice, people need to be
literally showered with propaganda (here I refer not to spreading of false
information, but rather using the term in an attempt to suggest aggressive
advertising) in the same fashion our potential competition approaches this
issue. And in this case, I mean we really need to give both the absolutely
best results, as well as the worst-case results (preferrably unique scores
for every type of audio hardware, thus putting some pressure on the hardware
makers as well making them start considering out-of-box Linux OS support as
well), and use them respectively in appropriate situations in order to
spread the word, always making sure to annotate them accordingly (i.e.
as-best-possible vs. worst-case) in order to avoid litigations of any sort
(gotta face the fact that we, at least in US, live in litigatious society --
Broadcast2000 being the living proof of that).

2) I am interested in what is the current latency achievable not only for
DSP stuff, but also for a MIDI aspect as well, since the last up-to-date
benchmarking of this sorts I was able to locate on the net is over a year
and a half old and not very comprehensive. I am also intersted in
cross-comparing different versions of kernels (i.e. 2.2.x vs. 2.4.x vs.
RTlinux etc.) in order to help newbies pick out the right stuff for their
purpose. Believe me, if anyone from the commercial world even starts
considering Linux for a multimedia app port, they will give up real fast if
they won't be able to find one place on the net that will be capable of
answering all their multimedia questions in a fast and efficient fashion.

3) I am looking for a good benchmarking software which will be capable of
objectively pointing this fact out to a regular user (read: person who
doesn't know anything more about computers than point-and-click stuff, and
is not inerested in learning anything more -- they just simply want to be
users, not administrators), in order to convince them this is really the
case. Thus, commercial software developers will suddenly realize that in
order to create software for Linux OS, they won't even have to worry about
licensing commercial ASIO or E-WDM drivers for their software to perform
well. They will have that already built into the OS for free! Just imagine
the repercussions of such developments! Running Sonar, or Cubase on Linux,
in combination with an already strong pool of existing high-quality free
audio apps. That would simply be incredible!

Subsequently, what could happen is if the apps started to be ported to
Linux, that could reorganize the priorities of the Kernel-devel community,
realizing that low-latency patches would become a necessity for a
main-stream kernel rather soon. It would be truly a win-win situation for us
musicians/composers. I am aware that some of my views are a bit
utopian-like, but concerning just how little effort this kind of addition
would require vs. what would be the potential benefits, I think that it
would be a real shame not to do it.

Well, enough of my rants. Just wanted to clarify my reasoning behind this
issue. Greetings to all fellow Linux users! Sincerely,

Someone had a good idea on alsa-devel to make an advertisement for the
lowest latency achieved on a linux system. It makes sense so I'm going
to add something to the LAU guide webring.

I would like to know two things.

1: What is the lowest latency achieved so far and on what hardware.

2: What is the most channels that have been successfully recorded with
no dropouts, for how long and on what hardware.

I will then magic up something snappy to represent these two sets of
figures.

Any ideas on how to present will be considered too.

Thx.
