Hi Alex, The actual test is 100 threads =C3=97 100,000 elements (10M lock-guarded=20 next() calls) I did tests with different config combinations ,=C2=A0 total work fixed at= =20 1,000,000 next() calls and varied only the thread count: =C2=A0 =C2=A0 config=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2= =A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0native x86-64=C2=A0 =C2=A0qemuriscv64 TCG = =C2=A0slowdown =C2=A0 =C2=A0 10 threads x 100k=C2=A0 =C2=A01.35s=C2=A0 =C2=A0 =C2=A0 =C2= =A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 15.5s =C2=A0 =C2=A0 =C2=A0 =C2=A0~11x =C2=A0 =C2=A0 100 threads x 10k=C2=A0 =C2=A00.10s=C2=A0 =C2=A0 =C2=A0 =C2= =A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 110.5s =C2=A0 =C2=A0 =C2=A0~1100x Trevor, do you have any suggestions how we can handle this situation ?
