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.
