Database performance is very very slow when I query metadata

Question

Hi,
I have installed Oracle 11G R2 recently and Its a oracle Standard edition single instance installation. When I run the below query it takes more than an 1minute to return the data. I have did another installation of oracle 11GR2 on on my laptop and it takes not more than 10sec. Why is this difference. Why is that query of meta data is taking so long. How to debug. Any help!
select component, final_size, end_time from v$sga_resize_ops where initial_size <> final_size order by end_time;
This is the query and its a direct select to a V$ table.
On one machine it takes 1min 31 sec.
