Hey, Maybe I find some time today to test a bit how we could solve that. But don't expect a solution right away. We know that could be an issue but it is not our first priority to fix that. Like Christian said, fetching the data in chunks could be one solution which could also be implemented by the app developer (you all sure did that for the old tree as Tobi said). I just checked the time which it takes to create 100000 qooxdoo objects and is not even 10% of the marshaling time. so maybe there is room for optimization there. I opened up a bug report for that: http://bugzilla.qooxdoo.org/show_bug.cgi?id=4699

But would that be enough? look at the timing of my playground example ... just creating the 'object' array takes less than a second ... I guess this is because there is no methods in the object :-) when writing code I try to defer expensive operations o the moment when they are actually needed (and then maybe cache the results). I would like a way for this pattern to work with the virtual widgets as well since their own design pattern is exactly this ... cheers tobi -- Tobi Oetiker, OETIKER+PARTNER AG, Aarweg 15 CH-4600 Olten, Switzerland http://it.oetiker.ch [email protected]<mailto:[email protected]> ++41 62 775 9902 / sb: -9900 ------------------------------------------------------------------------------ Index, Search & Analyze Logs and other IT data in Real-Time with Splunk Collect, index and harness all the fast moving IT data generated by your applications, servers and devices whether physical, virtual or in the cloud.
