| 2026-04-18 11:53:16 +0000 | <Milan_Vanca> | gentauro: I get that there is branch-prediction and choosing wrong branch slows execution down. However other processes don't "poision" branch prediction for other processes right? |

| 2026-04-18 11:47:57 +0000 | gentauro | this is a longer story and not really related to Haskell as you say |
| 2026-04-18 11:47:41 +0000 | <gentauro> | Milan_Vanca: from uni days, CPU's aren't all what you expect (except the PlayStation 3 cell processor). Most parts of CPU are used by branch-prediction |

| 2026-04-18 11:20:33 +0000 | <Milan_Vanca> | I would expect still 2x speedup so when CPU is busy par should be 1s. But it is not... interesting |

| 2026-04-18 11:19:39 +0000 | <Milan_Vanca> | I have found yet another interesting fact same CPU idle, seq = 0.6s, par = 0.3s, CPU busy seq = 2s, par= 4,3s |
