&gt; Hi folks,
&gt; 
&gt; I've been given an interesting realtime control system to build, and
&gt; my employer wants to evaluate both Linux (woohoo!) and Windows XP
&gt; Embedded (bummer).  I know some of you have some embedded/realtime
&gt; experience with Linux, so I'd like your opinions on this subject.  I
&gt; can't say much about the application itself, except that it will be
&gt; handling something in the neighborhood of 50Gbytes per day (that's a
&gt; G) of IP and serial traffic, and must meet hard deadlines on the order
&gt; of once per second (but a missed deadline won't kill anyone - this is
&gt; not a medical or aviation application. We can probably even recover
&gt; from a missed deadline, but that sort of thing should be kept to an
&gt; absolute minimum).
&gt; 
&gt; I'm thinking that a 2.6-series kernel would be the way to go with
&gt; this.  I understand 2.6 integrates the preemptive and low-latency
&gt; patches, and that 2.6 can be built in a VM-less configuration so as to
&gt; remove latency associated with demand paging.
&gt; 
&gt; Does anyone have any further suggestions or alternatives?  Also, is
&gt; anyone here in a position to evaluate the relative strengths of Linux
&gt; vs XP Embedded?  Personally I feel that the &quot;Embedded&quot; part of that
&gt; name is probably pure marketing hype, but I could be wrong.  It is hard
&gt; to see how Linux could possibly be a *worse* choice then XP in this
&gt; domain, though.
&gt; 
&gt; Thanks,
&gt;
