Working on some code that uses a Map to hold DB results.  One table has 9 million entries.
I'm constructing the hashmap with an initial size of 9 million, but it is still slow.

My guess is the slowness is when the .put() method has to search the hash index for a possible duplicate.  

Are there any other implimentations of Map that are geared towards large numbers of key/value pairs?

(at the expense of memory usage is fine, I will trade memory space for speed)
