HAC is slow

[ujohnny]

for project with
INFO [org.jetbrains.research.groups.ml_methods.algorithm.entity.EntitySearcher.prepareResult] - Generated 3965 class entities
INFO [org.jetbrains.research.groups.ml_methods.algorithm.entity.EntitySearcher.prepareResult] - Generated 26501 method entities

HAC didnt finish in 1 hour on 8cores CPU when ARI did

The reason for this is that HAC computational time is O((methods + fields)^2) in worst case and it requires the same amount of memory.

@ujohnny what is the name of the project? Because it seems that execution time mostly depends on connectivity of the components and classes but not only on number of entities.

actually memory wasnt a concern in my case.

[Ivan-Veselov]

What do you mean by that? IDEA had 1G of additional RAM or something? I'm asking because it can consume almost all available RAM and then very often run GC and this causes performance problems.

i use default configuration and idea's window about low memory wasnt shown there.
