One alpha will start about 138 threads to serve our clients(java client or go client or http client …).

Got it.

If I follow you one machine with three alphas, three machines with nine alphas, will not cause a higher system load?

No, the same load or less. But as I mentioned before, if you distribute the load between the 3 machines, even maintaining the same setup. Will help.
