Nice slides about seccomp and pledge

Update distcc build time@baalue

I have updated the measurements of the kernel build time on my baalue cluster (see Baalue-Distcc-Repo ).

The linux kernel build config is based on my a20 devices. The only difference between the 2 runs is, that it compiles a kernel on a A20 (Cubietruck) and on a A83T (Cubiertuck-Plus) as the master node. The Cluster (8 A20@Bananapi) is the same, so it`s interesting to see how the master node effects the overall performance.

Cubietruck-Plus:

make CC=distcc -j32 LOADADDR=0x40008000 uImage modules dtbs

real 15m56,545s
user 79m49,928s
sys 20m4,033s

Cubietruck:

make CC=distcc -j32 LOADADDR=0x40008000 uImage modules dtbs

real 68m48,674s
user 81m58,231s
sys 44m3,516s

It`s quite impressing to see the difference. The reason is, that the master node is under full load, because it has to distribute the jobs into the cluster. This takes computation time and therefore the cluster nodes are NOT under full load.
