Hi Rudriko, I can confirm the memory issue. I've opened a report for it:
http://bugzilla.qooxdoo.org/show_bug.cgi?id=5129 The CPU load problem is likely due to the browser having to evaluate and execute the response of every request as JavaScript since you're using the Script transport. If possible, you should try to reduce the amount of requests. If the data on the server doesn't change every second, maybe you can use a Comet approach [1] to push changes to the client only when necessary. Also, there might be ways to reduce the amount of data in each response. If only some of the property values change, maybe the server could only send the diff.
