rb260gs throughput question

Hello.
I am using your switch os products and i like it. Thank you.
But i cant find or understand one thing - what throughput i can get with rb260gs with default settings, For instance copy of a video file through that switch. No vlan. SwitchOS 2.6.
Can it give 1000 mbps throughput in this scenario?
Can port isolation settings(Forwarding) or vlan settings decrease switch performance?

Switching always happens at wire speed, so you can count on the 1000mbps no matter what.
