Build takes too long after adding commands for custom SBOM generation

[nikhilpatra]

We have mta application and corrected pipeline with steps required to create sbom's for mta application:
https://pages.github.tools.sap/hyperspace/academy/services/osc/beforeyoubegin/prerequisites/sbom/

Build time increased from 5 minutes to 8 minutes.

We needed to add custom SBOM generation to use for OSC and the default piper SBOM generation doesn't support the app. PR with added commands for sbom creation: https://github.tools.sap/DOX/dox-workflow/pull/288

Links to executions:

Here is a mtaBuild step which takes more than 8 minutes https://dev.azure.com/hyperspace-pipelines-2/DOX/_build/results?buildId=1410149&view=logs&j=3dc8fd7e-4368-5a92-293e-d53cefc8c4b3&t=d5e8b6b9-8492-5d92-9c22-7fb991ec1584

Whereas if we do not do SBOM generation It takes less than 5 minutes https://dev.azure.com/hyperspace-pipelines-2/DOX/_build/results?buildId=1408278&view=logs&j=3dc8fd7e-4368-5a92-293e-d53cefc8c4b3&t=d5e8b6b9-8492-5d92-9c22-7fb991ec1584

I was forwarded here via OSC->Piper.

Can you please have a look and provide some recommendations to optimize pipeline or any improvements that will decrease execution time?

Thank you in advance!
