KTorrent on NTFS

Hi I have a problem with KTorrent downloading files on to an NTFS partition. When I download, KTorrent first creates a file (I have selected to fully allocate disk space) in the destination directory. If the destination is on a NTFS partition, this process is extremely slow. After reading lot of documents on Internet and ntfs-3g documentation, I am using the following mount options in fstab: defaults,rw,umask=000,uid=1000,gid=1000,lazytime,big_writes,async But mount command shows: /dev/sda2 on /mnt/vault1 type fuseblk (rw,relatime,user_id=0,group_id=0,default_permissions,allow_other,blksize=4096) I get the same results if I mount manually using: ntfs-3g -o rw,umask=000,uid=1000,gid=1000,lazytime,big_writes,async,debug /dev/sda2 /mnt/vault1 Is this normal? I mean the mount options that I pass (specifically big_writes) are not reflected in the mount command output. How is NTFS performance for you all? Am I doing something wrong here? Thanks, Syam
