Understanding Memory consumption
Can someone please recommend a resource to help understand memory consumption in web browsers?
I also noticed that if I open some tabs in the Sencha Doc's application, and then cycle through the tabs repeatedly, the memory consumption of that page will also increase and does not appear to be garbage collected. This I don't understand because no addition data should be required for a tab that has already been viewed so what is the increase in memory being used for? Doing this with eight tabs can increase the memory consumption to over 1GB quite easily and the garbage collector is not reducing this significantly. Is that a problem with chrome or the web page? Can chrome's task manager be trusted?
In my application's case it is polling a server and updating a DataView every ten seconds. The memory consumption increases steadily - overnight it increased from an in initial 40MB to almost 4GB. All that the application does is read JSON formatted data from a server and populate a DataView with it every ten seconds.
It seems to me that there are issues with memory leaks in the sencha touch/Ext framework that make it unsuitable for applications requiring constant updates of their UI. Hopefully this isn't the case!
