Gli stati C-state sono numerati a partire da C0 (lo stato più superficiale in cui il core è completamente attivo ed esegue le istruzioni) fino a C6 (lo stato inattivo più profondo in cui un core è spento). Gli stati **P-state** controllano le prestazioni desiderate (in frequenza CPU) da un core. Gli stati P-state sono numerati a partire da P0 (l'impostazione sulle prestazioni più elevate in cui è permesso al core di utilizzare la tecnologia Intel Turbo Boost per aumentare la frequenza, se possibile) e vanno da P1 (lo stato P-state che richiede la frequenza di base massima) a P15 (la frequenza più bassa possibile). **Nota** AWS I processori Graviton dispongono di modalità di risparmio energetico integrate e funzionano a frequenza fissa. Pertanto, non offrono al sistema operativo la possibilità di controllare gli stati C e gli stati P. **Stati C e stati P** I seguenti tipi di istanza consentono a un sistema operativo di controllare

l'istanza per un carico di lavoro specifico. Le impostazioni predefinite degli stati C-state e P-state forniscono le prestazioni massime, ottimali per la maggior parte dei carichi di lavoro. Tuttavia, se l'applicazione traesse vantaggio dalla latenza ridotta al costo di frequenze single-core o dual-core più elevate o da prestazioni coerenti a frequenze più basse anziché frequenze Turbo Boost intermittenti, consigliamo di prendere in considerazione le impostazioni degli stati C-state o P-state disponibili per queste istanze. Per informazioni sulle diverse configurazioni dei processori e su come monitorare gli effetti della configurazione per Amazon Linux, consulta [Controllo dello stato del processore per le istanze EC2 Amazon Linux](https://docs.aws.amazon.com//linux/al2/ug/processor_state_control.html) nella *Guida per l'utente Amazon Linux 2*. Queste procedure sono state scritte e applicate per Amazon Linux; tuttavia, potrebbero essere utilizzate anche per altre distribuzioni Linux kernel di Linux di 3.9 o versioni successive.
