Re: [Emc-developers] EMC2 on Ubuntu 8.04 Hardy Heron - callfor tests

[jros <jr...@un...>]

Regarding latency test, I have recently made some experiments with about
5-6 different computers. One of them performed reasonably well and the
others has the infamous SMI problem.

I searched the wiki for a solution and I found one, that requires
recompiling, after following the instructions, NO SUCCESS.

The I searched Google and found this

https://listas.upv.es/pipermail/rtlinuxgpl/2007-April/000609.html

It is a simple and very little standalone utility that allows to switch
off entirely the SMI.
I where able to perform good latency test in all the computers using
that trick.

I think that such a utility could be included with the new release.

Also I think that it can be reference in the wiki section related to
latency and SMI problems as an alternative quick solution.

Bye,

Javier
