"OProfile is a low overhead, system-wide performance monitoring tool. It uses"
" the performance monitoring hardware on the processor to retrieve "
"information about the kernel and executables on the system, such as when "
"memory is referenced, the number of L2 cache requests, and the number of "
"hardware interrupts received. On a &MAJOROS; system, the "
"<filename>oprofile</filename> RPM package must be installed to use this "
"tool."

"Many processors include dedicated performance monitoring hardware. This "
"hardware makes it possible to detect when certain events happen (such as the"
" requested data not being in cache). The hardware normally takes the form of"
" one or more <firstterm>counters</firstterm> that are incremented each time "
"an event takes place. When the counter value, essentially rolls over, an "
"interrupt is generated, making it possible to control the amount of detail "
"(and therefore, overhead) produced by performance monitoring."
msgstr ""
"Molti processori includono un apposito hardware di controllo della "
"prestazione. Questo hardware è in grado di rilevare la presenza di alcuni "
"eventi (come ad esempio l'assenza in una cache, di dati richiesti). "
"L'hardware normalmente viene rappresentato da uno o più "
"<firstterm>contatori</firstterm>, che vengono incrementati ogni qualvolta si"
" verifica un evento. Quando il valore del contatore varia, viene generata "
"una interruzione, rendendo possibile un controllo della quantità dei "
"dettagli (e quindi dell'overhead) forniti grazie al controllo della "
"prestazione."

"OProfile uses this hardware (or a timer-based substitute in cases where "
"performance monitoring hardware is not present) to collect "
"<firstterm>samples</firstterm> of performance-related data each time a "
"counter generates an interrupt. These samples are periodically written out "
"to disk; later, the data contained in these samples can then be used to "
"generate reports on system-level and application-level performance."
msgstr ""
"OProfile usa questo hardware (oppure un sostituto basato sul timer, in casi "

"raccogliere degli <firstterm>esempi</firstterm> di dati relativi alla "
"prestazione, ogni volta che un contatore genera una interruzione. Questi "
"esempi sono registrati periodicamente su di un disco; più in avanti i dati "
"contenuti in questi esempi, possono essere usati per generare dei riporti "
"sulla prestazione a livello del sistema e delle applicazioni."
