RE: ecos == slow ??

It's only an opinion, but I'd say that you're probably missing something. 
Our experience with eCos has been that (with our applications) it provides 
comparable performance to a well known commercial RTOS. I'm assuming that 
you ran the VM on the Compaq under embedded Linux, and then under eCos to 
get the timing comparison.

I'd recommend that you use whatever diagnostic features you have available 
to gather some timing information on the sequence of events that occur as 
your program starts up.

Cheers
