Lots of generated queries I enabled devel to Display query log

UPDATE: this problem only happens for logged users

I found that the Frontpage generate 900 queries. 

**67** of them generated by the **Locale** module


and 

**480** of them are of the type: **DrupalDatabaseCache::set**


How can I track this problem?

I read that I should disable the i18 module, but I can't do this since it is a multilingual site and I there are other modules that need the i18 module.

This only happens in the Frontpage in other pages the queries downs to 300.
Problem was in theme. I change to the site Bartik theme and the problem was gone. 

I'm using the commerce kickstart distribution if that helps someone. I run into other issues in the past with the frontpage in this distribution. I just remember that and that is why I thought it could be a problem related to the theme. The theme of this distribution has some lines in the preprocess file and that imho may be the source of the problem.

I my situation I will use other theme since I don't need a responsive theme at all.
