Adastrip Performanace

Hi,
I am using ADASTRIP to extract Adabas files (about 100 files) Would it be efficient to strip all the 100 files using say about 10ADAstrip Runs (extract 10files in one go) or call ADASTRIP once per file.
I know ADASTRIP uses the RABNS to extract the files out. Are the RABNs read sequentially? If yes, may be should I group files which are contained in the RABNS close to each other…

Thanks in advance…

Cheers,
