distcc questions

I am currently compiling a new 4.7.4 kernel with gpio sysfs and a realtech wireless module. I'm using distcc on a bananapro client and distcc with x-toolchain on a 64bit slackware-14.2 box with a 6 core processor.

So I have used -j8 in my make command

Code:

make -j8 CC=distcc bzImage modules

How should the compiling be shared out? I thought that there would be more than 4 jobs on the workstation but there very rarely is.

Code:

  
  8432  Blocked                                                            [0]
  8437  Blocked                                                            [0]
  8391  Preprocess  ring_buffer_benchmark.c                     192.168.1.2[2]
  8374  Preprocess  async_pq.c                                  192.168.1.2[4]
  8401  Compile     vmaster.c                                   192.168.1.2[5]
  8420  Preprocess  uid16.c                                     192.168.1.2[6]
  7896  Compile     clk.c                                         localhost[1]

Also would it better/quicker to not list localhost so that all work goes to 192.168.1.2 and would things be any quicker if I also listed my other banana pro which is also up on the lan?

If you look at the "dbuild" script in the same location, this is more or less the same one I use. localhost isn't included: if distcc cannot compile on the x86 it'll fail back to localhost anyway.
None of my ARM machines are in the distcc pool - they're too slow.
