TIFF conversion

We have several large TIFF's imported to DW from an older system. The viewer displays them fine but downloading as a PDF is not always successful. Note, a typical TIFF may be 7000 pages and many hundreds of MB on disk. 

Acrobat could be one alternative but seems slow on conversion. Does anyone have experience with huge TIFF's, converting to PDF?

Acrobat is painfully slow with conversion.
You are better off with a command line utility such as 2PDF:

I have used their 2TIFF utility in the past and it is robust and fast. I imagine their 2PDF product is also good.
