In our last post, we looked at some common memory issues and how to troubleshoot them. Today we're going to go over excessive paging and memory bottlenecks.
We've talked about issues with the page file in several posts - something to bear in mind is that although you want to have enough RAM to prevent excessive paging, the aim should not be to try to prevent paging activity completely. Some page fault behavior is inevitable - for example when a process is first initialized. Modified virtual pages in memory have to be updated on the disk eventually, so there will be some amount of Page Writes /sec. However, when there is not enough RAM installed, there are two issues in particular that you may see - too many page faults, and disk contention.
