	Tier 1: Fondamentale e Architetturale

	1. Utilizzare Hardware Fisico Adeguato (NIC) (Lo strato fisico è il collo di bottiglia finale; non si possono inviare 100Gbps su una porta da 10GbE.)
	2. Abilitare sendfile on; (Abilita il trasferimento "zero-copy" dei file, riducendo drasticamente il carico sulla CPU.)
	3. Sfruttare Storage NVMe ad Alte Prestazioni (Lo storage deve leggere i dati più velocemente di quanto la rete possa inviarli.)
	4. Massimizzare la RAM di Sistema per la Page Cache di Linux (Usa la RAM libera come cache super-veloce per i file richiesti di frequente.)
	5. Usare un RAM Disk (tmpfs) per i Segmenti Video Live (Elimina l'I/O del disco per i file live temporanei, operando alla velocità della memoria.)
	6. Aumentare i Buffer di Memoria di Rete del Kernel (net.core.mem) (Permette al kernel di gestire più dati per ogni connessione, saturando link ad alta banda.)
	7. Aumentare i Descrittori di File (File Descriptors) di Sistema e per Processo (Evita errori "Too many open files" gestendo migliaia di co
