Dear all,
I am using the ECLiPSe C/C++ API in my applications. 

In general my applications spent 80% of overall execution time on constraint
solving by using ECLiPSe function calls. 

I observed also (e.g. /usr/bin/time) that each application takes much more
as kernel time than user time (one order of magnitude, e.g. 0.1 sec as user
time, 1 sec as kernel time). Which is the reason? I assume is related to
ECLiPSe. Could you confirm and explain me the grounds?

Best regards,
