sysbench

W odpowiedzi na prośby dotyczące testów kerneli przeprowadziłem 3 próby następującego testu, którego wynik można obejrzeć poniżej.



Zainstalowałem sysbench poleceniem:
sudo apt-get install sysbench
i wykonałem dla każdego z kerneli następujące pomiary:
sysbench --num-threads=$(grep 'model name' /proc/cpuinfo | wc -l ) --test=cpu run > test
sysbench --num-threads=$(grep 'model name' /proc/cpuinfo | wc -l ) --test=memory run >> test
 Pierwsze polecenie bada CPU, a drugie Pamięć. Ten tajemniczy na pierwszy rzut oka zapis:
$(grep 'model name' /proc/cpuinfo | wc -l )
odpowiedzialny jest za sprawdzenie ilu wątkowa jest nasza maszyna, teraz całe polecenie powinno być już zrozumiałe:)

A oto wspomniane wyniki:

różnice na moim sprzęcie mnie zaskoczyły, fakt, że są widoczne gołym okiem przy zestawieniu z tymi liczbami jest zrozumiały:)

Namawiam do sprawdzenia na waszych zabawkach. Może zdobędę się na heroiczny wyczyn i zbuduję coś co ładnie to zbierze w tabelkę:) może jakiś "ficzer" NeteXta powstanie w ten sposób w przyszłości :)
