    Windows VPS Eats Ram?

    Hey,

    We have a windows VPS server with 4GB RAM on it, it currently has 12 websites on it, IIS runs using 3.5GB RAM... is this right?? Or does it sound wrong to you?

    If so how can I reduce it or find out why?

    Check what the websites are running (and if they got a lot of visitor) and try to optimize the server (stop unneeded services etc).

    We have servers on Win 2008 Std which has only about 3-4GB RAM and it runs perfectly well. Nothing of a problem. 1 of them has about 200+ sites on there and it's still doing good with only 4GB RAM. Not too sure what happened to yours but I am suspecting that 1 of them much be really really using or doing lots of processing and etc.

    Something wrong with your VPS.
    Windows 2008 itself uses about 500 MB RAM with IIS installed.

    Windows 2008 does RAM caching so you need to check the 'actual' usage.

    Not to mention that if you're running .net apps through IIS, you have to contend with the CLR's GC and how that works. For the most part, late generation objects will just sit there until the next GC flush.

    There's so many performance counters you can plug in just to watch how it unfolds. What you want to look at is the 'Private Bytes' to make sure it doesn't continually increase over prolonged periods.

    I know that Windows will use all the RAM available on the system and use it for a file cache.
    Just because your server shows you're using a lot of RAM does not mean it needs more RAM.
