Getting query result set faster from table

Hi Experts,

In one table, I've nearly 150,000 records.

When I am doing SELECT column1,column2,column3 FROM tableName (NOLOCK)

its taking nearly 9 minutes to get the complete result set.

I've one clustered Index and one Non clustered index 

Is there any way to get the result set faster.

Regards
