In case of performance for multithreaded applications, development (Java) and virtualization (Parallels 11), what's better - upgrading to 10.9 Mavericks or El Captain? (or Yosemite) ?

Now I'm on 10.8.5, MacBook Pro 15", i7-2.0x4, on SSD with 16GB RAM

P.S. upgrading needed as Parallels 11 doesn't support 10.8

    You'd be better off upgrading to the newest system. You would be getting the newest tools, and would have access to the newest items, making future upgrades a much greater span of time – user2277872 Feb 25 '16 at 10:46

Go El Cap. The marginal performance decrease (especially on your machine) is near zero compared to 10.9. You'll get better support, newer features, newer apps, etc.

  • where is the main performance degradation of El Cap then - in OpenGL apps (games, video etc.) ? I was also looking other discusstions about it. – yetanothercoder Feb 25 '16 at 12:30
  • @yetanothercoder Huh, I haven't seen any threads about that. Can you link the thread you're referring to? – JMY1000 Feb 25 '16 at 17:51
  • I've seen some concerning fps degradation, ex: eu.battle.net/wow/en/forum/topic/16070567139 – yetanothercoder Feb 26 '16 at 17:09
  • @yetanothercoder Interesting, I don't know anything about that–I haven't experienced any degradation personally. – JMY1000 Feb 26 '16 at 18:00
