    I realise this is an old chestnut but although I found your document very interesting it didn’t help me solve my problem (probably because I misunderstood or misread). I am running a Win2003 SP2 server as a VM (Hyper-V) on which I have an ACCESS database. My VM Host machine has a 4-core processor but I read Win2003 is only comfortable with 2-Cores. So the 2003 machine VM is given 2-Cores and 4096 RAM dynamically increasing up to 6144 I gave the Win2003 server 100% of the 2-cores CPU – On the Win2003 I have two partitions each with a pagefile of 6142 But when I monitor the machine it is using (in bursts when ACCESS is doing something) between 50%-90% of the CPU while the pagefile is flatlining Commit Charge Total = 1492nnn Limit is 16709204 Peak is 1898500 What have I overlooked? Really appreciate any guidance – thanks Jon

    Win2003 loves CPU cores, so don’t be afraid to give it more than 2.

    Normally the Access-database is just a file, that you need the Access-application to access.

    Are you running the Access-application on the Win2003-machine? Or have you just placed the Access-database-file on the Win2003-machine-network-share and running the Access-application on another machine?

    I’m guessing you are running the Access-database-application directly on the Win2003-machine (Maybe using Remote Desktop). Do you have multiple users running the Access-database-application simultaneously?

    The Access-database-application is only 32 bit, so it can only use 2 GByte of RAM. Having assigned 4 GByte of RAM, should be more than enough if only a single user is logged on and only running the Access-database-application.

    If your Acess-database-application is not able to perform, then you should probably have someone profile the application and fix the issues. If the RAM or Harddisk was the issue, then it would not be using 50-80 pct CPU.
