Here's what I get on a my UP 5.3-STABLE with ULE and PREEMPTION (thr & lc_r
not installed, hence not tested):
[lofi at kiste]:~ > time ./aqueue_linuxthreads -n 10000000
pusher started
poper started
real 0m19.157s
user 0m4.639s
sys 0m5.545s
[lofi at kiste]:~ > time ./aqueue_kse -n 10000000
pusher started
poper started
real 0m32.619s
user 0m31.858s
sys 0m0.532s
Still slower, but already lower than factor 2.
