Beim Versuch, einen NFS-Server mit dem Bonnie-Benchmark zu testen, habe ich festgestellt, dass eine Zeile der Ergebnisse Latenzwerte sind. Ich frage mich, ob jemand erklären kann, was diese Latenzwerte bedeuten. Vielen Dank!
Beispielhafte Bonnie-Ergebnisse (Latenzlinie hervorgehoben):
mshamma@hs1:/mnt/hs18/bonnie$ sudo bonnie -u root -c 100 -s 100000
