In a 2.5G wired LAN, use Directory Opus to transfer files between two computers, from the local computer to the other, with an uplink speed of 130 MB/S and a downlink speed of 250 MB/S Using Win11's resource manager to transfer files from the local computer to the other party, with an uplink speed of 200 MB/S and a downlink speed of 280 MB/S. May I ask why Directory Opus is a bit slow? Can this issue be resolved?
Try increasing Preferences / Miscellaneous / Advanced [Filesystem]: copy_buffer_size
(In the future, we'll switch Opus to using the high-level CopyFileEx API for copying files where possible, since this seems to be the only way to copy data at full speed on Windows with some network setups. Other methods can be slower due to the OS not buffering the data properly. It's rarely noticed since most programs don't report the speed they can read/write at, or use CopyFileEx.)
