Best Way Of Dumping The Rows Of A Table To Another Table

Hi,
I have two table as follows

Tabel Cat
{

ID
Update Datetime
}


Table Master
{

UniqueId
Cat Datetime
}

I wanted to insert millions of rows from Cat to Master table and can be achieved from the following query




Code SnippetIINSERT INTO Master (UniqueId, Cat )
SELECT ID, Update from Cat



Question : Is there any better way do achieve the same operation with better performance mean to say that the execution should be less than the time it takes to execute the above statement

Thanks for your time
