    Umbraco on Hyper-V VPS-Hosting, memory

    Hello, is there anyone, who succesfully use Hyper-V hosting for more umbraco sites? I'd like to move more hosted sites to one VPS-Hosting, but I'm specially aware of memory. Is 512MB enough?

    The limits will depend on how busy your sites are and how many custom controls and stuff you have implemented.

    For starters I would make sure to run all the Umbraco websites in the same application pool. .NET will start a worker process for every application pool and every worker process needs a reserved amount of memory.

    Downside of this approah: if one of your websites goes down and your app pool crashes, all of your websites will go down and restart.

    However you will save memory resources when using this approach.

    512Mb is not enough! I think I've seen Casey talking about each site consuming for about 70/80 Mb of RAM (not sure if that included sql server or not)?

    I'd opt for at least a 1Gb of RAM machine and making sure to limit sql server resources to a maximum, otherwise it'll eat all RAM available.

     

    Hope this helps.

    Regards,

    You could also schedule an automatic application pool recycle every once or twice per 24 hours. It's not very elegant but it will free up some memory.

    The answer is... depends.

    Windows requires about 400 MB itself.  If you are running SQL Server locally as well, expect about 100 MB at least, with another 20 or so per db. 

    With a single site, I would go with at least 768, but typically 1GB will do you more justice..

    Be sure to limit SQL Server if you are using it, otherwise, it will try to overtake your system.
