If you really want to continue hierarchical clustering, I belive that ELKI (Java though) has a O (n^2) implementation of SLINK. Which at 1 million objects should be approximately 1 million times as fast.

Hierarchical clustering deals with data in the form of a tree or a well-defined hierarchy. The process involves dealing with two clusters at a time. The algorithm relies on a similarity or distance matrix for computational decisions. Meaning, which two clusters to merge or how to divide a cluster into two.
