Best practices for paging files on Windows Server 2008 R2

By Chiphead® ·
With servers continuing to ship with increasingly large amounts of memory these days it seems appropriate at this point to revisit the common standard of making a page file 1.5 times the amount of system memory. If you purchase a server with 128GB's of RAM is it really necessary to create a file that's 192 GB's in size? That seems just a little ridiculous. So my question is, what best practices are you following these days on your systems running Windows Server 2008 and 2008 R2 in regards to sizing your page file? Going through some various posts I thinking of using the 1.5 times the memory guideline until the page file hits 4 GB's. After that I would occasionaly check on (or hopefully just have Operations Manager watch it) the percent usage of the paging file using performance monitor. If it's a high percentage I would just incease the amount of physical memory.
