Dell D6000 - Slow ethernet

[AlbanRampon]

Hello,
This is peculiar and not expected. Especially the second report.
Would you please be able to use the third link in my signature to gather the machine details and other logs?
Also, please specify what network equipment (brand, model and network speed) the Dell D6000 is connected to.
I can then create a bug report for investigation. To have better chances of reproducing this, we will need to select either close or identical equipment. An internal reproduction is likely to be necessary for debugging.

Final question, how do you measure the speed? Is that using a local FTP server, moving files through a Samba/Windows network shared driver, external website test?.

Kind regards,
Alban
