Yes Daniel, it happens especially during the metadata parsing. The 
trouble is yum is in version 2.4.3.
The C metadata parser sounds great. I'll try it in future Yum versions.

I'm not a developer but anybody knows that C is great language in terms 
of performance.

¿Is Yum written totally in Python or I'm wrong?
