 Hello,

 I need to do a back-up of files served by an amd64 NetBSD node (5.2.0),
 and, in case of problem, this back-up has to be readable directly by
 Windows nodes. So I use external USB connected disks (USB 3.0; the
 server has USB 3.0 ports too), formatted as NTFS, and I use
 fuse/ntfs-3g.

 But the write performance is quite poor (1.5 Mb/s).

 Is there anyway of speeding things up? From searching around, it seems
 that the bottleneck is with the driver by itself.

 TIA

are you referencing specific links from searching around?

I believe you that it's slow, but I'm sure it would take some research
to make any improvements.

Are you using the character device (e.g. /dev/rsd1a) or the block device
(e.g. /dev/sd1a) for ntfs-3g?

Is the umass(4) attaching via a USB 1 or USB 2 controller?

Searching around is really that: via any searching engine. There are
several threads about the poor performance, mainly for Linuces, some for
Apples. And it seems that there is a commercial offer that advertises
better throughput... So I guess that the speed of the open driver is
not optimal, and probably not a focus...

The block device.

USB 2 controller (the mainboard offers several ports, with color
differences on the slots; some USB 1 or 2, some USB 3; the disk is 
connected on a USB 3 port).
