I have been using PDF Indexer for four years. A single load test on z/OS never finished, dying after two hours.
Just ran a test earlier today on a 2500 page PDF.
AIX was just under 4 times as long as a Windows server. I think Windows took about 38 seconds, and AIX took about 2:16.
We load 500-700 container PDFs five days a week year round. Indexing on Windows servers when loading to z/OS, we used 8 indexing servers, and the load process finished in about three hours. Now going to AIX, we use three Windows indexing server , and load completes in about 90 minutes. And uses about 1/38 the storage. z/OS expanded PDFs by a factor of 19. AIX reduces them by half.
