Solr Query Performance between with and without q=*:*

Could anyone explain me if there are diff in performance between these 2 queries ?

q=field1:xxx

and 

q=*:*&fq=field1:xxx

Also, it would be good if you know about documents for Solr performance turning and post them here.

Thanks,

fq utilizes filter cache which allows all the subsequent queries to be fetched from cache rather then the actual index.
