10 y old machine with rotat. disk; ./configure --enable-debug --enable-profiling --enable-optimization=-O2 (if you really want release mode I can rerun, but it takes lot of time to recompile :) case 1 (#if 1) a) empty cache (echo 3 > /proc/sys/vm/drop_caches) #pmprof# getIcon: 6.32 ms, count=221, total=1.40 s b) reload with cache after a) #pmprof# getIcon: 1.53 ms, count=221, total=337.32 ms case 2 (#if 0) a) empty cache #pmprof# getIcon: 2.33 ms, count=223, total=519.26 ms b) reload with cache after a) #pmprof# getIcon: 955.58 us, count=221, total=211.18 ms What is interesting is not time for math but time for new document! Even with cache I am waiting for about ~5s for new document to appear. We had to screew something badly because 2.3.x gives ~0.5s (or I am paying for --enable-debug --enable-profiling).
