I have found the reason of high usage of cpu.

The user guide of kepler missed some details about the addition sample, so
after I build a model as it said, the usage of cpu is very high.
Fortunately, I found it's a paramter about iteration in sdf director cause
the problem, the default value of it is 0. After I change the value to 1,
everything is fine. 

Thank you very much!

I downloaded a new copy of Kepler-1.0.0beta1 (with jre), installed it, and
also ran it with no problem, so I see no evidence of a memory leak. 
I have 2GB of memory, but the Windows Task manger reports that only a bout
520 MB is being used when I am running Kepler.

So I have no idea why you are having the reported problem! The only thing I
can suggest is perhaps your download was corrupted, so you might try
downloading the installer again and reinstalling?
