High CPU in some TSS modules calling the ICSF CSNBOWH SHA-1 hashing function.
While running a new COBOL program that calculates SHA-1 hashes using the ICSF CSNBOWH service, it has been noted
that the job uses a larger than expected amount of CPU resource.
Further investigation has revealed that a large large portion of the CPU consumed by the job is used by various
TSS modules such as TSSMVS2, SAFRT001 and TSSSFRVT. Is there a reason for this?
