As I discussed previously on IBM-Main, I've played a bit with ABO. Some observations:
-- The more CPU-intensive the program, the more it will benefit from ABO. Heavy I/O hitters not so much. -- There is virtually no overhead in an ABO-optimized program. I've some folks use the term 'dynamic' for an ABO environment. ABO 'digests' an existing load module and saves the new version in a separate location. At execution time, there is no additional run-time setup or preparation. -- I've not heard of any incorporation of ABO into the standard source/load management products like Endevor or Panvalet or ISPW. -- Probably the biggest advantage of ABO is that the run-time library may be PO or library depending on the code. COBOL V5/V6 requires library (PDSE), which may impact a shop's migration and sharing practices. . .

A quick search on the internet gives a lot of info This thread maybe helpful https://groups.google.com/forum/#!topic/bit.listserv.ibm-main/fh1g4n7f5_Q From within this thread ABO is going to make a V3/V4 program faster, in general, because it has access to ARCH(up-to-10), in your case, instructions which the V3/V4 compiler does not have access to. It is also able to use some optimization techniques not available with OPT in V3/V4 (learning for the optimizations in V5, which in turn learned from optimizations for Java). A program may be "flat" (before = after) but that would seem fairly unlikely, and any such program would likely not be a CPU heavy-hitter. Caveat. It would be possible that the ABO has initial "overhead" larger than the original program that affects CALLed programs. I don't know. Not seen it. Just sayin'. https://www.ibm.com/developerworks/community/blogs/invisiblethread/entry/Give_your_COBOL_applications_A_BOost_with_the_flip_of_a_switch?lang=en As far as I know you run your program through ABO process which can reduce the need to recompile with V5 and above Cobol and you can get some benefits.
