[OpenIndiana-discuss] USB 2 performance

[Aurélien Larcher]

Hi,
There is indeed a much newer version of ntfs-3g on Jean-Pierre André's website: 2015.3.14AR.1.
He posted very good results earlier this year.
Having these in oi-userland is on the TODO list and would be great.
Thanks for your report.
Best,

Aurélien
