Here's the best and worst times I get on my linux laptop. These are with 2.064.2 dmd and gdc 4.9 with 2.064.2 On Ubuntu x86_64: ~/dmd2/linux/bin64/dmd -O -release -inline -noboundscheck -unittest singleton.d Test 2 time for SyncSingleton: 753.547 msecs. Test 2 time for AtomicSingleton: 22290.3 msecs. Test 3 time for SyncSingleton: 254.968 msecs. Test 3 time for AtomicSingleton: 22903.3 msecs. Test 6 time for SyncSingleton: 510.118 msecs. Test 6 time for AtomicSingleton: 23970.9 msecs. Test 8 time for SyncSingleton: 480.175 msecs. Test 8 time for AtomicSingleton: 12827.9 msecs. ../bin/gdc -frelease -funittest -O3 singleton.d Test 0 time for SyncSingleton: 458.605 msecs. Test 0 time for AtomicSingleton: 1985.87 msecs. Test 1 time for SyncSingleton: 334.097 msecs. Test 1 time for AtomicSingleton: 2030.29 msecs. Test 5 time for SyncSingleton: 355.765 msecs. Test 5 time for AtomicSingleton: 1040.87 msecs. Test 9 time for SyncSingleton: 295.145 msecs. Test 9 time for AtomicSingleton: 1272.22 msecs. It seems like gdc and dmd are similar for SyncSingleton. AtomicSingleton is significantly faster for gdc, but not as fast as SyncSingleton.
