Performance-Tuning

Hi,

I have a table with the fields data(timestamp), region and url (varchar)
This table has 4.5mio entries a day. To reduce them I use the following
insert-statement.

insert into msreduce select distinct on (region, url) '1-16-2001',region,url,count(client) from microsoftlog where date
>'1-16-2001' and date < '1-17-2001' group by region,url 

My question: Could this be optimized?
