If you have an older ntfs-3g release than version 1.328 then the slowness is an ntfs-3g limitation and you should upgrade to at least version 1.328 or preferable version 1.417.

The maximum supported NTFS file size and the volume size is 16777216 GB (16 EByte) but typically your hardware and Linux limits this to 8192-262144 GB. Windows can't support more either at the moment (maximum 262144 GB = 256 TB).
