Performance issue

[mingmin95]

Hi @porterehunley, I ran the example, 10000 node take 16s, 60000 node take 6min, not as fast as the report said
May I ask where the problem may have occurred?

Do you mind sharing what architecture you're running on? Also, can you tell me how long the "initial dissimilarities" took for 60k points?

6 minutes is too long but you should be able to speed that up by increasing the no_processors from 1 to the number of cores available on your machine.

@porterehunley thanks for the reply, increase the n_processors from 1 to 8, 60k points still need ~3min, and the architecture is as follow:
