Cachier slows down box provision if multiple provisioners are used

Provision slows down if multple provisioners are used.

For example: puphpet/puphpet uses 12 provisioners to build up a box. I was expecting provision speed improvement but instead provision slowed three times because of multple "cache buckets" reconfiguration.

  config.vm.provision :shell, :path => 'puphpet/shell/check-puppet-modules.sh'
  config.vm.provision :shell, :path => 'puphpet/shell/install-ruby.sh'
  config.vm.provision :shell, :path => 'puphpet/shell/install-puppet.sh'

  config.vm.provision :puppet do |puppet|
    puppet.facter = {
      'fqdn'             => "#{config.vm.hostname}",
      'ssh_username'     => "#{ssh_username}",
      'provisioner_type' => ENV['VAGRANT_DEFAULT_PROVIDER'],
    }
    puppet.manifests_path = "#{data['vm']['provision']['puppet']['manifests_path']}"
    puppet.manifest_file  = "#{data['vm']['provision']['puppet']['manifest_file']}"
    puppet.module_path    = "#{data['vm']['provision']['puppet']['module_path']}"

    if !data['vm']['provision']['puppet']['options'].empty?
      puppet.options = data['vm']['provision']['puppet']['options']
    end
  end

  config.vm.provision :shell do |s|
    s.path = 'puphpet/shell/execute-files.sh'
    s.args = ['exec-once', 'exec-always']
  end
  config.vm.provision :shell, run: 'always' do |s|
    s.path = 'puphpet/shell/execute-files.sh'
    s.args = ['startup-once', 'startup-always']
  end

  config.vm.provision :shell, privileged: false do |s|
    s.path = 'puphpet/shell/execute-files.sh'
    s.args = ['exec-once-unprivileged', 'exec-always-unprivileged']
  end
  config.vm.provision :shell, run: 'always', privileged: false do |s|
    s.path = 'puphpet/shell/execute-files.sh'
    s.args = ['startup-once-unprivileged', 'startup-always-unprivileged']
  end

  config.vm.provision :shell, :path => 'puphpet/shell/important-notices.sh'
