I've read a bit about the strategy applied by Windows to paginate RAM to the pagefile. Apparently, Windows may decide to paginate to disk unused pages from the processes' working set, to ensure that there's available RAM to attend additional needs as soon as possible.
Our server runs a controlled number of processes, around 250. The memory usage of each of them is controlled, so the maximum used RAM by all of them is around 32 GB. The server has 64 GB, which is more than enough to ensure that there's no need to paginate to disk memory committed by additional user sessions and other applications we may run at a given moment (perfmon, profilers, etc...)
These processes highly stress the disks, which cause the average seconds per operation to raise to even 100ms. This slows a lot manyu operations and create bottlenecks in our system. My hypothesis is that it is possible to alleviate a bit the disk stress if we remove the pagefile. Windows should then stop paginating RAM at all. This would cause problems when there's no more RAM available, which we'll ensure that can't happen.
Is this hypothesis valid? Does anyone have tried this in a production environment?
Edit: I see that the question got downvoted. While that's fair and helps creating a quality Q&A and knowledge sharing site, it would be really good if the people that downvoted add some comments explaining why. Without feedback there's no improvement.
