--Sig_Jip+y.ksvo1mSrs3gahAUT8 Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: quoted-printable Hello. I have tried sysutils/fusefs-ntfs (version 1.0) and had a maximum write speed of 1.2MB/Sec. Reading is a little faster: 2MB/Sec. There were some discussions about this in the ntfs-3g forums, and they said was fixed in the new beta version (now it's stable, see official site), note that by default it uses an option that is not available on FreeBSD's mount_fusefs, so try with "-o no_def_opts". http://forum.ntfs-3g.org/viewtopic.php?p=3D1330&sid=3D8e59dcb7050a15378eb93= d5659c04409 It makes no difference for me. However I found the following which says "the reason for the slow copy on FreeBSD is the lack of buffer cache for block devices which should be solved in FreeBSD 7.0", and mentions "ublio", a library for user space cache which can be used with it, made by the author of fuse4bsd. The rest of the thread is irrelevant for the matter. Is this change going to be MFC'ed to RELENG_6? http://forum.ntfs-3g.org/viewtopic.php?p=3D1153&sid=3Dcde9378447762e86345a8= 9130fd267d5 Unfortunately I couldn't make it work, if someone has time, please take a look. It would be really appreciated. I tried contacting the port maintainer and fuse4bsd/libublio author without response. Also I have posted this to freebsd-hackers@ without response, maybe this is the right place for this kind of discussions. Thanks and Best Regards, Ale P.S.: please CC me as I'm not subscribed. --Sig_Jip+y.ksvo1mSrs3gahAUT8 Content-Type: application/pgp-signature; name=signature.asc Content-Disposition: attachment; filename=signature.asc -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (FreeBSD) iD8DBQFGKX95iV05EpRcP2ERAms9AJ9bz2ioT/wPvKoXv1Dg+UXdVxSANACfciYC iuUt/L6Box5Ft4Jm3BbP+H8= =PLS4 -----END PGP SIGNATURE----- --Sig_Jip+y.ksvo1mSrs3gahAUT8--
