    With 4GB or more RAM, you can forget the pagefile. A 2GB file should be there but it will quasi never be used (under normal PC usage).

    I found out that with 8GB I can safely turn off but keep 1 GB because some programs (like Photoshop) do insist on having some and it doesn't take too much space on disk. Widows does some righting on disk so ust turning PF off is not much of performance improvement anyway.

    Your right David my mistake on the mention of Pagefile, Virtual memory in my post as this would use up disk space not the RAM.
    As virtual memory uses disk as memory so not the issue for this OP.

    The issue of the need for a page file when you have lots of memory is a curious one, obviously from a technical point of view with 16 + GB of ram it's unlikely that it will be needed and the old rule of 150% of ram installed as the ideal for a Virtual memory store is not valid.

    However, some applications are designed to run with a page File, and if there is not one available will spend memory cycles looking for the page file and can actually cause lag.

    Due to this I always set a fixed page file of about 512 MB to 1 GB even with machines with plenty of RAM

    I think the minimum for the pagefile is 16MB. Some processes seem to use the pagefile mechanism for something but do not actually write to the pagefile. If you look into the Resource Monitor > Memory tab, you will see the occasional hard fault. But those are dummy page faults if you have enough RAM. Nothing goes to the actual pagefile.

    I suspect you meant 350 MB ???

    I'm glad I got involved with this thread - Out of interest I checked my settings and realised when I moved my Page file off my system SSD I must have accidentally clicked on System Managed rather than my normal set and forget fixed option.

    As a result the system had decided I needed to have a 48 GByte Page file!!! My system is currently idling along with about ten tabs open in Firefox plus a few background apps and is using about 10% (of 32GB), have reset to it's supposed optimum of 8Gbyte, (the Page file is on an empty 500GByte scratch drive I use for various photo editing), so no worry about space

    I did a lot of work on OS/2 and OS/2 Warp back in the day - It had a true 16 bit support when windows was still at 8 bit and was used for the real time data acquisition systems I was designing / maintaining at that time - Nice bit of kit in it's day
