Optimize Performance

About this task

You can optimize performance in the following ways:
  • Optimize virtual memory: Through the use of paging files, Windows allocates space on your hard drive for use as if it were actually memory. This space is known as virtual memory. This topic describes how to optimize the virtual memory on the Historian archiver computer.
    Note:
    If the paging file is set to grow dynamically, your system may experience severe performance problems during runtime. To ensure optimal performance, the Initial Size and Maximum Size values for the paging file must be the same so that the paging file does not grow dynamically. For more information on creation and sizing of Windows paging files, refer to Microsoft Windows Help.
  • Optimize the server performance: If the file sharing and printer sharing options on the computer on which you want to install Historian is set to maximize data throughput, it can lead to excessive paging when dealing with large files, which can interfere with applications like Historian. You can change these settings to optimize the performance.

Procedure

  1. To optimize virtual memory:
    1. Access Control Panel, and then select System > Advanced system settings > Advanced.
    2. Under Performance, select Settings > Advanced.
    3. Under Virtual Memory, select Change.
    4. In the Initial size and Maximum size fields, enter a value equal to three times your physical memory.
    5. Select Set, and then select OK.
  2. To optimize server performance:
    1. Access Control Panel.
    2. Select Network and Sharing Center.
    3. Select the network that you use.
      The <network name> Status window appears.
    4. Select File and Printer Sharing for Microsoft Networks, and select Properties.
    5. Select Properties.
    6. Ensure that the Maximize Data Throughput for Network Applications option is selected.
    7. Select OK.
