Have you test with a VV not in a RCG? |

Hi guys, i have tested some things now. 32/64 bit , 2008r2 , win7 a vv not in an rcg etc etc... it is very strange and everytime the same problem , if i copy files like 1,5g the process takes 1-2sec. very fast. if i try to copy files like 20g , at the start the copy process is very fast too but after a few seconds of copying i got about 60/mb/s. i also could confirm this performance when i take a look to statvlun -vvsum VVname Cur Avg Max Cur Avg Max Cur Avg Cur Avg Qlen SSD_R1 t 55 134 948 31700 68602 375898 2.33 2.90 574.2 513.3 0 maybe someone got an advice for me... thank you |

when you say copy, i hear robocopy... did you try /MT ? Otherwise you could simply use IOmeter. |

hi, for the copying : just tested over the gui. also have tested with i/o meter several times. performance looks good here , i have the issue with just ordinary copying processes i hardly believe that. |

Hi druck.at! Did you find a solution for this issue? I currently have similar situation for 3PAR 8200 with 16 SSD cMLC 480GB drives. |
