Hi all

I have a problem with optimizing my export to the network volume. DaVinci 15b3, PC connected with NAS in other room through 1Gb router. When I simply copy files from local drive to NAS the transfer rate is 1Gb/s but during export this rate goes down to 250-300 mb/s

I wonder why it is happening.

This is quite normal. Copy command uses buffering/does requests ahead (it's quite heavily optimised).
BM exporter won't do these things and it's quite typical that it's much slower than copy task.

I lso assume you are not reading end exporting to the same NAS.
You can try enabling jumbo frames if this is supported on ALL your devices in the chain.

Of course NO
