Signature and Certification Processing Time

Objective

Set clear expectations for how long signing and certification operations should take.

Guidelines

Under normal operating conditions, a signature or certification operation is expected to complete within this range:

Expected processing time

Minimum about 300 milliseconds (0.3 seconds)

Maximum about 1.5 seconds

Treat this range as the normal processing window for signing and certification.
If your system regularly takes longer than this, investigate—it may point to an integration, network, or configuration problem.
