Hi, all:  
I have installed callgrind/kcachegrind in my kubuntu for monitoring  
the process performance of my RoR program.  
But I encounter a problem as a jackaroo of callgrind/kcachegrind. How  
could I monitor my ruby contoller or model files? Is there any tips?  
Thanks very much!!

regards  
ye

NO one have used it before? Then how could people evaluate the  
bottleneck of RoR program?
