Does that mean it’s using the filesystem which is causing the bottleneck?


Although it is the Subject of this thread, there is no evidence from what you have posted that you are measuring file upload or download speeds.


I have nothing further to add, and will withdraw from the discussion.

Oh, you're right.
Of course it doesn't involve the filesystem, so that souldn't be the bottleneck

No one an idea? 1. Maybe the two sets of results are mis-labelled? 2. Have you done similar independent measurements of the network performance of workstation.local - maybe the bottleneck is there? 3. You are getting 65% of a Gigabit connection.

A suggestion for forum users who have been registered for more than 25 hours, to avoid there being future 'problematic' posts.

Mute.

Silence.
