Are you referring to the microITRON native OS and the eCos native OS, or 
are you referring to the microITRON API layer provided with eCos?

I understand from our customers using the eCos uITRON layer that 
performance of the eCos uITRON is roughly the same as the native uITRON 
with minor differences in certain areas.  eCos uTIRON is slightly slower 
and larger, as could be expected running a compatability layer on top of 
eCos, but the timing differences were negligible to our customers anyway.

I would therefore expect eCos native applications to be smaller and 
faster then uITRON native applications (given the removal of the uITRON 
API layer) but have not done any direct comparisons and am not aware of 
any other comparisons between uITRON and eCos.

eCos is freely available for download, including tools, so please try 
eCos and compare against uITRON for yourself.  Also feel free to publish 
the results here :-)
