We are using tesserat (which includes libtiff) to OCR tiff files. For certain files I am seeing warnings such as:

TIFFReadDirectory: Warning, TIFFstream: invalid TIFF directory; tags are not sorted in ascending order.

TIFFReadDirectory: Warning, TIFFstream: unknown field with tag 32934 (0x80a6) encountered.

The file is still processed fine, but my question is will this cause processing to take longer or produce less accurate information?

No, and no.

They are just warnings about odd or non-compliant aspects of the file.
