Some tips for speeding up mock via its configuration:

• /etc/mock/site-defaults.cfg
  • Disable the package state plugin:

    config_opts['plugin_conf']['package_state_enable'] = False

  • Parallelize builds:

    config_opts['macros']['%_smp_mflags'] = "-j17"

  • Improve ccache hits between package version builds (may break -debuginfos!):

    config_opts['files']['etc/profile.d/zz-local.sh'] = """
    unset CCACHE_HASHDIR
    """

  • Compress ccache:

    config_opts['plugin_conf']['ccache_opts']['compress'] = True

  • Use lzo compression for root cache:

    config_opts['plugin_conf']['root_cache_opts']['compress_program'] = "lzop"
    config_opts['plugin_conf']['root_cache_opts']['extension'] = ".lzo"

• Per-repo config files
  • Parallelize (de)compression within rpmbuild:

    config_opts['chroot_setup_cmd'] = 'install @buildsys-build pigz lbzip2'
    config_opts['macros']['%__gzip'] = '/usr/bin/pigz'
    config_opts['macros']['%__bzip2'] = '/usr/bin/lbzip2'
