different speed in different platform

[lancexiang]

with same mesh file, i tested in MacOS, Windows, Linux with loop subvision and decimate, here are results: macos and windows:

vertex: 321098, faces: 642208
loop:  10.47s
decimate:  8.97s

while linux

vertex: 321098, faces: 642208
loop:  35.74s
decimate:  21.39s

I don't know what happens and how to fix the linux time-consume.

Just to be sure, are you using the same machine but with different OS? Could you please share the mesh and the code you are running?
