Does anybody have an ides why ndisk64_75 results and ganglia graph results are totally different.
following was the ndisk test that was run
ndisk64_75 -f monsterfile -R -r80 -b 16k -t 600
ndisk gave me 99701.4 IO/Sec. however Ganglia for the same test period shows the maximum 7.9K IO/sec (7900 IO/Sec). where is the hiccup?
