I have seen many examples of programmers wasting CPU cycles. For example

SCAN ALL
IF this and that
replace field with something
endif

if not this and not that
replace field with somethingelse
endif
ENDSCAN

It is much faster to optimize that

REPLACE field with something for this and that
REPLACE field with somethingelse for not this and not that.

In other words, are you scanning all records and calling the conversion of data or are you targeting the conversion? If I remember correctly, you are trying to convert PDF files? You can improve things by declaring the dlls at the start of the entire process rather than at each file....

Is the one PRG the slowest part of your system? If so, post that prg and let's see what can be done.
