IDMS Archive Journals to Disk/Blocksize Optimization

My company is in the process of converting the IDMS archive journals from tape to disk and being asked to optimize the disk/DASD block size.

Currently, the archive journal offloads that are on tape have an LRECL=32760 and BLKSIZE=32760.

Does anyone have a general rule or calculator for determining and optimizing the LRECL & BLKSIZE for the journal files onto disk?

Any support or guidance on this subject would be greatly appreciated.

Thank You.
