Depends on what you put into your kernel configuration file.
A kernel optimized for a system can lead to better performance.
This has been true especially for systems with fewer resources.
Note that only a specific optimization level is allowed for
"buildkernel" (standard compiler optimization), while
"buildworld" can usually utilize a higher optimization leve.

You can find more here:

This approach is interesting if you're working with embedded
systems. On regular home PCs and servers, this is hardly done
today, but of course still supported and possible.
