This test is doing a brute-force mapping. Coupled with changes to
QCOMPARE last year, this now allocates and deallocates a lot of memory
per iteration. On my Sandybridge, it takes two minutes to run:
111136.781153 task-clock # 0.999 CPUs utilized
371,692,633,238 cycles # 3.344 GHz
182,641,818,708 stalled-cycles-frontend # 49.14% frontend cycles idle
57,951,552,830 stalled-cycles-backend # 15.59% backend cycles idle
477,216,332,971 instructions # 1.28 insns per cycle
# 0.38 stalled cycles per insn
86,959,637,669 branches # 782.456 M/sec
309,185,237 branch-misses # 0.36% of all branches
111.264868818 seconds time elapsed
Changing the iteration step from 1 to 5 reduces the runtime to about 5
seconds.
