Implement the application startup time probe as mozilla did in this (helpfully MPL2-licensed) patch: http://hg.mozilla.org/mozilla-central/rev/dfdf3e5dc749 , and hook that up with the profiling tinderbox Moggi is already running for Calc.
CCing developer list to Easy Hacks missing this.
Migrating Whiteboard tags to Keywords: (EasyHack DifficultyInteresting SkillCpp) [NinjaEdit]
JanI is default CC for Easy Hacks (Add Jan; remove LibreOffice Dev List from CC) [NinjaEdit]
Re-evaluating the EasyHack in 2022 This enhancement is still relevant. Startup measurement with timestamps to achieve the detailed time taken for each part of the startup is very helpful to understand the cause of the slow start in order to improve startup time.

I want to work on this issue, However, can you please tell me what this "profiling tinderbox" means?

If you mean a unit test, it does not seem necessary to me. I don't know what others think, but if you want to work on this, just go ahead instead of waiting for a consensus. A test can always be added later.
Venetia's patch on gerrit, if someone would like to review: https://gerrit.libreoffice.org/c/core/+/163965 Venetia, once merged, how would one access those measurements?
In this patch I have added the measurements as a SAL_INFO log. A further enhancement could be exporting it to a interface.
