I was going through https://github.com/sympy/sympy/wiki/new-release in preparation to cut the release candidate, when I get to the "speed of import" section. I compared the test_import tool against SymPy 0.7.1 and the 0.7.2 branch, and there appears to be a significant slow-down (by almost 4x).
Can other people reproduce this? If so, we need to figure out if it is possible to bring this back down again. sympy(sympy-0.7.1)$%$./bin/test_import Note: the first run (warm up) was not included in the average + std dev All runs (including warm up): [0.632580041885, 0.142980098724, 0.144616127014, 0.18177986145, 0.153340816498, 0.146248817444, 0.152235031128, 0.147120952606, 0.149618864059, 0.147889852524, 0.146507978439, 0.146991014481, 0.148049116135, 0.149016857147, 0.146153926849, 0.149012088776, 0.146345853806, 0.145620822906, 0.156076908112, 0.146780014038, 0.148214817047, 0.146635055542, 0.148654937744, 0.14654302597, 0.146838188171, 0.14808511734, 0.147293806076, 0.148097991943, 0.149609804153, 0.148839950562, 0.147723913193, 0.146723985672, 0.151859045029, 0.147171974182, 0.148344039917, 0.14845085144, 0.147562980652, 0.151570081711, 0.200988054276, 0.150926113129, 0.152683973312, 0.149338960648, 0.148150920868, 0.149286031723, 0.146691083908, 0.147687911987, 0.145917892456, 0.14581489563, 0.150799036026, 0.147582054138, 0.145636796951] Number of tests: 50 The speed of "import sympy" is: 0.149922 +- 0.008985 sympy(sympy-0.7.1)$%$git co 0.7.2 Previous HEAD position was 556fe55...
