Dear List, You will find below the health report of today. I removed two important bottlenecks: node translations and computing absolute bounds. Layouting nodes is more then 100 times faster! You can now do a "view nodes: (1 to: 20000)" in an easel without having the time to take a coffee! Here is the comment of Mondrian-Alexandre_Bergel.352 -=-=-=-=-=-=-=-=-=-=-=-= Major speed improvement: - MOGraphElement>>absoluteBounds uses now a cache. This helped speeding up Mondrian by 35% - Make MORectangleShape>>display:on: use absoluteBounds instead of absoluteBoundsFor:, which speeded the UI up of 14% - optimization when translating nodes (MOGraphElement>>translatedBy:), we gained a significant speedup when layouting nodes -=-=-=-=-=-=-=-=-=-=-=-= Report produced on 2010-01-23T18:17:13+00:00 Benchmark ManyNode (simple rendering of nodes) : 100 nodes => 3 ms 200 nodes => 5 ms 300 nodes => 6 ms 400 nodes => 7 ms 500 nodes => 9 ms 600 nodes => 10 ms 700 nodes => 12 ms 800 nodes => 14 ms 900 nodes => 15 ms 1000 nodes => 17 ms 1600 nodes => 28 ms Benchmark ManyEdges (simple rendering of edges) : 10 edges => 2 ms 20 edges => 6 ms 30 edges => 12 ms 40 edges => 28 ms 50 edges => 48 ms 60 edges => 74 ms 70 edges => 115 ms 80 edges => 169 ms 90 edges => 254 ms 100 edges => 335 ms 200 edges => 4356 ms 300 edges => 35919 ms 55.54 % of methods are covered Progress from last time: -0.1 % Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.
