Petalinux compiles slowly - what to do?

Speed up with parallel builds, incremental builds, sstate cache cleanup, SSD, fewer packages.
Common Speed-ups
PetaLinux is Yocto-based, so the first full build is inherently slow, but daily iteration can be much faster: parallel builds, incremental builds via the sstate cache, keeping the project on an SSD, and trimming unnecessary packages.

Avoid deleting the sstate directory casually — it is exactly what makes incremental builds fast; clean it only when the cache is corrupted or a full reset is intended.
