I would never run without a page file for a number of reasons. You’re limiting your apps to the amount of RAM installed and no more. If you have a page file, they can use more ram than is available and page it in and out. If you ever run out of RAM without a page file you will bluescreen. If this is a multi user OS, you will run out of RAM very quickly. In my experience on multi user os, performance without a page file, or with a very small one is garbage even with a ton of ram. Performance is also poor with letting windows manage it, as expanding the pagefile is horribly slow.

Fair enough. I need to go back and revisit this then. There have been setups where I didn't use it to be honest. I don't recall issues. But you make valid points.

Mike I agree with all those reasons you listed. Question: It's still a good idea to manually SET the Min and Max for the page file, on the Master Image? Sounds like you're suggesting "Yes"...

This may help Greg. https://www.citrix.com/blogs/2011/12/23/the-pagefile-done-right/

Thanks Ray, this is a great article. The thing I'm wanting to confirm is, you set the Page File on the MASTER the way you want it to be configured on all the thousands of VDAs, right? I'm 99% sure the answer is "Yes", but I'm someone who makes no assumptions and I always check things to be as sure as I can possibly be... Thanks!

I totally understand. I was doing some testing last week. But when I did do the page file on the master, I can confirm once you set it on the master, it will following down to the pvs targets. Which will be placed on the D drive or next available drive for WC for PVS. I had to resize the disk as well as I wasn't using a good size. The page file will need to be smaller than the write cache drive or the drive needs to be sized properly for the page file and write cache for pvs targets.

OK great, thanks. That's actually a really good tip: As you and I have chatted, we're going to start a PVS-on-Azure pilot in a week or two, and so these types of Config bits are good to know

Yea keep me posted on that I'm really curious on what challenges or differences you may see. Good luck as well

Cool, will do!

Yeah, I set the min and max to the same size so that it doesn’t resize the pagefile but only because I think performance sucks during a resize. I don’t have any metrics to prove this though.

OK no problem. I am one who accepts (and tests) recommendations from other guys who've been doing this awhile. Thanks! We'll start looking at that for our Master Images.
