I don't know if anyone else has noticed (perhaps most of you don't leave the tab(s) open as long as I do) but there appears to be a memory leak in this site. Memory usage rockets (easily consuming nearly a GB of active memory) and the page can become unresponsive/sluggish. Eventually the page process needs forcibly ended using Chromes task manager, or the tab needs to be closed.
I haven't been able to pin down a cause since it never feels like acting up when I run the memory profiler on it, but the number of times I have been forced to crash the page is too high to ignore. Generally it behaves for a while, but will spontaneously begin to climb and lock up. I have yet to catch it in the act, so I can't be certain of the cause.
For reference, Gmail and Google Drive (two heavy web apps) only need 150-300megs each, and hold that number pretty constantly while idle. This forum shouldn't need to consume anywhere near that amount of memory (similar sites are 50-90 meg).
