Hello all:
 
I'm part of a research group at the University of Toronto doing research using UML.  I'd like to measure the performance of applications running in UML vs. on Native Linux.  Since the implementation of sys_time seems to end up being a call to gettimeofday on the host system, it would appear that a clock tick in UML is the same as a clock tick on the host system. 
 
Thus my question is would using gettimeofday in UML be a good way comparing performance in UML to performance on the host?  Are there any better ways of measuring how long something takes in UML?
 
Thanks in advance,
 
David Lie
