    -> Current Activity
    ---> Process Info

    They will effect the performance but you need to check from where they are coming...
    If your application is not closing connection after the request they will be there in SQL and SQL will not cleanup.
    Every connection takes some memory ...I don't remember the value at this time...

    A SPID set to Sleeping status basically indicates that the process has completed executing however it is waiting for further instructions from the application. They can become a serious problem is they are blocking out other SPIDs you can delete them one by one or create a script to delete them all for you.
