The document said yes. However, what does bootstrap actually do that can make compiler faster?

Assuming the gcc you are bootstrapping is newer than your system
compiler, it is quite likely to be better able to optimize itself than
the older system compiler.

Hello.
In case of openSUSE, we leverage both bootstrap-lto config with 'make profiledbootstrap'. That utilizes
profile-guided optimization. Moreover, when the latest compiler provides a new optimization, then
only using bootstrap can benefit from it.
Hope it helps,
Martin
