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? Jonathan Kollasch

I believe you that it's slow, but I'm sure it would take some research to make any improvements. 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... -- Thierry Laronde tlaronde +AT+ polynum +dot+ com http://www.kergis.com/ http://www.renaissance-francaise.fr/ Key fingerprint = 0FF7 E906 FBAF FE95 FD89 250D 52B1 AE95 6006 F40C

The block device. Is the umass(4) attaching via a USB 1 or USB 2 controller? 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). -- Thierry Laronde tlaronde +AT+ polynum +dot+ com http://www.kergis.com/ http://www.renaissance-francaise.fr/ Key fingerprint = 0FF7 E906 FBAF FE95 FD89 250D 52B1 AE95 6006 F40C
fuse ntfs-3g on USB poor performances
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.
