Test - Linux

Linux non dispone della stessa varietà di benchmark presenti su piattaforma Windows, ma ha comunque un'ampia scelta di strumenti di diagnostica a system-info integrati che permettono di radiografare la propria macchina in un modo estremamente preciso.

In più, il nostro Asus Eee PC dispone di comode interfacce grafiche preinstallate che possono servire a questo scopo: ci riferiamo innanzitutto alla suite Diagnostic Tool, facilmente accessibile dalla linguetta Settings di Easy Mode, e al sistema di Hardware Detection del Control Center di KDE (Full Mode). Entrambi consentono di verificare l'hardware presente sul notebook e di accertare eventuali malfunzionamenti, ma le informazioni non sono dettagliate come vorremmo.

Per questo ci siamo affidati ad una serie di comandi e programmi da command line ben noti a tutti gli utenti Linux, che ci hanno restituito un'immagine estremamente approfondita dei componenti hardware montati sul nostro notebook. Partiamo dall'individuazione della versione del kernel Linux installata:

$ uname -a
Linux asus-731711046 2.6.21.4-eeepc #6 Mon May 5 11:38:34 EDT 2008 i686 GNU/Linux

Proseguiamo poi con l'elencazione di tutti i dispositivi installati o collegati al netbook:

$ sudo lspci -vv

output lspci

$ sudo lsusb -v

output lsusb

$ lshw

output lshw

Per raccogliere qualche informazione sui drive SSD montati sul nostro EeePC 1000 ci siamo serviti di hdparm. Come di consueto sia il modulo allo stato solido on-board che quello su scheda PCIE minicard sono marchiati Asus-Phison. Il primo ha una capienza di 8GB, mentre il secondo può immagazzinare 32GB di dati. Utilizzando l'argomento-t, hdparm ci fornisce anche una sintetica indicazione delle performance in lettura dei due dischi: hanno una velocità analoga, con un lieve vantaggio per il drive da 8GB (31,41MB/s contro 29,29MB/s).

Memoria (1GB) e reti non riservano particolari sorprese. Il Wi-Fi funziona correttamente e, grazie ai diversi tool grafici a disposizione, cercare una rete e autenticarsi è davvero un gioco da ragazzi.
