Importing binary file is toooooo slow...

I'm using v.4.2.1.0 --

I am importing (wrong word?) binary data from a file:

<< Utilities`BinaryFiles`

y = ReadListBinary["filename", SignedInt16, 
ByteOrder->LeastSignificantByteFirst];

The file is only 34k bytes long but it takes 16 seconds to do it. This 
isn't a slow machine so clearly I'm doing something wrong again.

I would appreciate any suggestions on how to make this thing sizzle as I 
feel sure it can.  Right now I'm dead if I have to do a big file.

Thanks
