Resumo direto: Se você não controla suas threads… suas threads vão controlar seu sistema. E normalmente, no pior momento possível.

Quer ir além? Configure programaticamente. Use Runtime.getRuntime().availableProcessors() como base… Mas cuidado: Em Kubernetes, isso pode te enganar bonito. (esse é o tipo de detalhe que derruba sistema “bem feito”)
Se você ainda usa @Scheduled no default… você está apostando contra sua própria aplicação. E provavelmente já está perdendo só não percebeu ainda. Porque aqui vai o detalhe que pouca gente fala: O Spring executa todas as tasks agendadas em uma única thread Agora pensa comigo
Isso é o tipo de coisa que separa: 👨💻 código comum de 🧠 código inteligente
Traduzindo pra vida real: Você sai disso ❌ “recalcular tudo toda hora” Pra isso ✅ “resposta pronta o tempo todo”
Você está calculando mediana do jeito mais lento possível… E provavelmente nem percebeu.
