Issue/Introduction

Description:

Does the CA Top Secret Control Option SHRFILE(YES) affect security performance if not really sharing the CA Top Secret Security File?

Solution:

If not really sharing the CA Top Secret Security File, SHRFILE(NO) should be set.

SHRFILE(YES) adds increased I/O due to the enqueuing and dequeuing of the Security File to keep the file's integrity.

SHRFILE(NO) disables the enqueuing and dequeuing of the Security File, which is not needed when not sharing the Security File.
