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
