SUMMARY
Please only checksum the ISO image if the user asks for it, not automatically.

If K3b tries to checksum an ISO image, it slows down the system by replacing the data in the memory cache with the ISO image, and it also wastes CPU power.

STEPS TO REPRODUCE
1. open ISO file with K3b

OBSERVED RESULT

K3b starts checksumming the ISO file automatically, without it being requested by the user.

EXPECTED RESULT
Don't checksum the ISO file automatically. Replace it with a button where the user can launch a checksum if they wish.
