icecc

NOTE: icecc daemon has to be run on localhost. Instead of this all jobs will be spawned locally with i.e. -j 100 

sudo apt-get install patchelf icecc icecc-monitor

Example performance gain (make -j14 vs make -j 100): 

bitbake nativesdk-qemu
 
#
# ICECC_PARALLEL_MAKE = "-j 100"
#
bitbake nativesdk-qemu -c cleansstate
time bitbake nativesdk-qemu
 
real	3m58.270s
user	0m0.942s
sys	0m0.153s
 
#
# ICECC_DISABLED = "1"
#
bitbake nativesdk-qemu -c cleansstate
time bitbake nativesdk-qemu
 
real	7m21.235s
user	0m1.019s
sys	0m0.209s
