Limitation of Sub-Site under Site Collection. RRS feed

  • Question

  • Hi,

    Is there any limitation of Sub-Sites under a Site Collection. The reason I am asking is in context of development. What is the limit of sub-sites, which will allow us to run do development and run the code without any memory usage issue with number of concurrent user is somewhere between 500- 6000.

    Also is there any limitation in sub-site nesting, I mean the level of sub-site within a Site.

    Regards,

    Paddy74

  • There is no firm limit on the number of sub sites in a site collection or the number of levels.  In general you should observe the following guidelines for SharePoint 2007.

    • All sites in a site collection are stored in the same content database.  You should limit the content database size to about 100GB maximum.
    • Its usually best to limit the hierarchy to less than about 5 levels.  This is more based on navigation clicks than performance, but is a general rule of thumb.
    • Performance as it relates to memory will be very dependent on whether you are running a 32 bit or 64 bit OS.  A 64 bit server OS supports more available memory.  A 32 bit OS is limited to no more than 4 GB.

  • SharePoint has a general rule of thumb of 2000 items per container at the same level, this is mainly due to the UI, so if you aren't displaying all 2000 with the standard views, navigation you can have more items at the same level. 

    You should be fine to have many levels of hierarchy.  Performance etc depends on your development environment.  Typically your development environment should be limited to the developers in the project and you should use a test or UAT environment.
