QNAP TS219 slow when access from windows 7 64 bit

[davjava]

I have a problem, when I try copy large number of small files from NAS share to Windows 7 64 bit PC Client transfer rate is very slow.
If I try copy small numer of big files transfer rate is normal.
Some one help me?
Thank's very much in advance

What are you using to copy? If you use the windows commandline xcopy or robocopy tools, do you see the same thing?

Yes, same problem also using xcopy or robocopy tools.

Same happened for me after the latest 3.6.1 firmware upgrade (TS-219+). Copying over network dropped from 60MB/s under 20MB/s; usually 10-15MB/s. Anyone on QNAP - can you test this and fix it asap!

My office enviroment:

-TS-219+ (2x Samsung 1TB F3) 9k jumboframe enabled
-couple i7/2600k with Asus motherboard with integrated Intel NIC`s
-Lenovo T420 with integrated Intel NIC
-HP Procurve 1800-24G

Robocopy is slow in the copy-direction from w7 -> NAS. Then the CPU (TS-210) runs at 50%. (there are also some small Files zu mirroring / compare ). From NAS -> w7 is normal speed. Robocopy is a default tool to copy and mirroring with Windows - also for the business branche.

I noticed the same.
Before the last update, I could copy from Win 7 64 to the TS-219+ with upto 70mb/s, now it dropped below 20.
From TS-219+ to Win 7 is still the same, 80+mb/s.

Is there any way to go back to a previous firmware?
The last update is just bad...

Same here,

Last update gives slow network speeds. Even from Windows XP and Windows 7 32 bit systems.
Anybody know a solution except from downgrading ?
