How can I speed up the build process?

• Use -j switch to enable parallel builds
• Use local mirror to avoid downloads (advanced build options)
  

  CONFIG_LOCALMIRROR="file:///home/username/mirror

• use local feeds (src-link) instead of downloading with git

Build may FAIL

The build process can be accelerated by running multiple concurrent job processes using the -j-option:

make -j 3

• Use the standard formula <your number of CPU cores + 1>
• If this produces random build errors try compiling again without the -j-option

If the build fails with errors that include [s-attrib] Killed and [all-gcc] Error 2 while compiling gcc, this indicates you are out of disk space or RAM. This could be likely if you are building within a virtual machine with < 1 GB RAM allocated and no swap.
