FIELD DESCRIPTION FOR VM MODE Procs r: The number of processes waiting for run time. b: The number of processes in uninterruptible sleep.
During the 18 seconds of displayed stats, you have 12 seconds in which 1 process is waiting for run time. Which process is that, and where is it waiting for ?
Is your custom excecutable compile project causing this or does a simple compile task display the same slowdowns? As a small bench test with a source we all can download, try to compile bison-1.75.tar.bz2 :
# ./configure ; time make ... make[1]: Leaving directory `/home/stock/tmp/src/bison-1.75' 37.33user 3.64system 0:40.66elapsed 100%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (121059major+64165minor)pagefaults 0swaps
