Topic: Speed differences in PDFLib and CLIBPDF

I am tasked with evaluating various PDF libraries for inclusion in our Report Writing Application. I have integrated both the PDFLib and CLIBPDF libraries (in different instances). Utilizing the same code to interface to these libraries I have noticed a drastic speed difference. To create a 17 page report with PDFLib it takes approx 4 seconds while CLIBPDF takes approximate 2:45 to produce the same report (output is acceptable in both cases). I have run the profiler on both instances (the report writer code is a combination of c and C++) I have noticed for instance that the display text function (_PDF_SHOW() and CPDF_textshow() for PDFLIB and CLIBPDF respectively) have drastic differences in execution time but perform the same functionality ( to the PDF Layman that I am) PDFLIB takes .005 ms while CLLIBPDf's takes 13.11 ms.
My question to you guys is Am I missing something here. I do not see how my code could be causing this difference as I use the same code for both libraries. Thanks for reading this and Thanks for all the help this forum provides.
