it might be helpful to know how much memory you have. you can go to Windows Explorer, find your PC, and right click and view the properties to see details of your machine.
i opened up task manager (make sure you look at more details), and then just navigated through the identify page just to see what was happening. what i see is that each observation i look at seems to increase total memory load, each new set of 100 increases it, and there are only occasional small decreases in memory load. so that page can quickly start to suck up a lot of memory if you’re going through hundreds at a time.
so this seems to be a classic case of either a memory leak or memory bloat. these kinds of problems are sometimes difficult to troubleshoot and fix. so, to me, it does seem like a system problem, but i don’t know how easily it can be resolved.
i notice that the identify page doesn’t seem to load the next page by actually loading a new page. instead, the same page just loads new information and replaces the information on the existing page with the new loaded data.
that said, if i actually refresh the page (using the browser’s refresh button), that seems to clear the memory usage back to a reasonable level. so refreshing occasionally may provide a way to mitigate the issue for now.
