A2000 Compute Best Practice

Preface

If Your A2000 Compute or A2000 Cloud Desktops (VDI) experiences degraded performance, this is due to inconsistent network connectivity between Your office and the A2000 Cloud.  This degradation in performance is due to congestion at the carrier, insufficient bandwidth subscription and/or unmanaged bandwidth on Your local Area Network (LAN).   The web is a shared medium and performance degrades during heavy web traffic.

If you are thinking of using the web to connect to your VDI, refer to the following:

  • Smaller offices or home offices (10 users or less) – Subscribe to the largest feasible web connection possible, with a minimum of 10 Mbps synchronous bandwidth for each VDI user.  (i.e. 5 users over the web will require 50 Mbps).
  • Large Offices (10 users or more) – Subscribe to a private dedicated connection as this allows full end to end management and guarantees consistent network connectivity, with a minimum of 5 Mbps synchronous bandwidth for each VDI user.  (i.e. an office of 12 users with a private dedicated connection will require 60 Mbps).

VDI practice and network settings

  1. Reboot your VDI weekly. VDIs are no different that physical desktop and require weekly reboots to clear memory leaks caused by bugs in applications.
  2. Limit browser toolbars. Installing multiple browser toolbars leads to slow web browsing and slow VDI performance due to add wares streaming similar weather and radio channels.
  3. Streaming video in full screen HD will consumes heavy bandwidth as much as 50 Mbps per stream per user or more. This can dramatically slow your VDI and your office. Keep videos streaming in Window Mode and refrain from streaming music, weather channels and other non-business heavy graphics applications.
  4. Make sure you are using the most updated VMware Horizon client on your desktop. Optimized VDI performance is achieved via the latest VMware Horizon client and further optimization can be achieved with the use of a PCOIP thin client such as the 10Zig 7817q-4630  or an HP t310 G2 Zero Client.
  5. Have your IT department prioritize PCOIP and Blast traffic on your router, firewall or switch. This is done by prioritizing traffic for ports TCP/UDP 4172, TCP/UDP 8443 on any devices with egress and ingress to the Internet. For more information on PCOIP prioritization see Teradici Design Checklist.
  6. Install the PCOIP Statistics Viewer this empowers you to see local network or carrier issues that might be affecting the performance of your VDI.
  7. Use wired network connections vs. wireless whenever possible. A wired connection is always faster than any wireless.
  8. Don’t store personal files or load non-business apps locally (i.e. iTunes music). Store your business projects on your server drive.
  9. Switch Windows to a Basic Theme under Advanced Performance Options. Turn off all Windows animations and use a plain solid colored screen background. To better consume bandwidth.

    This Section Applies for Users Running AutoDesk Revit – Optimizing Revit Workflows on VDI

    When using Revit in a virtual environment, consider these best practices.

    1. For optimal performance, user profiles should be as small as possible. Ensure enough free disk space is on your VDI proportionate to the size of your central model(s) you are creating a copy of locally.  Periodically clear temp files (%temp%), Autodesk temp install directory (C:\Autodesk\), Downloads, and local copies of central models (in ‘My Documents’ usually) including _backup folders correlating with the rvt files.
    2. Rendering uses a lot of system resources and works best when run on a dedicated client computer or utilizing a back-end distributed rendering system such as v-ray swarm.
    3. Upgrading Revit models consumes a lot of memory and can have an adverse effect on other users working on the same server. If you are going to be doing a lot of it, you may consider upgrade models on a separate computer running Revit before opening these models in the VDI environment
    4. Turn off shadows for all printed views if not absolutely necessary.
    5. Use section boxes or crop regions to limit working area.
    6. Set detail level to Coarse or Medium.
    7. Set the following in Revit Options:
      • Set Tooltip Assistance to “none.”
      • Turn off the ViewCube.
      • Turn off 3 options for SteeringWheel Text Visibility.
    8. In general, the following characteristics of a building model can affect performance:
      • Complex geometry
      • Multiple parametric relationships
      • Multiple constraints
      • Linked files

    Inside Revit Models

    1. Open the model at least once a day creating a new local copy by browsing to the central and not using the recent files list.
    2. Address warnings regularly and correct them. The more warnings will lead to slower performance.  The continual tracking of these warnings by Revit will increase the file size and drastically affect the model performance if left unmanaged.  Warnings that should have priority to be addressed are those involving calculations… such as areas, rooms, spaces, joined elements, analytical elements, and MEP systems.
    3. Purge regularly and avoid loading too many families in the model that you don’t need because this increases file size. Purge out what you don’t need.  You can always add something if you need it from your family library.  If there are families in your project that you don’t have in the library, but don’t need in the current project, you can export them out and save them to your library freeing up space in your model.
    4. Avoid locking / constraining too many elements
    5. Put revit links on their own worksets so that they can be unloaded completely from memory when opening a project rather than just using the unload link feature which removes it from sight, but it is still in system memory.
    6. Link CAD files rather than inserting directly into your Revit project. When links are no longer needed, remove them rather than just unload.
    7. If you must have elements directly imported from CAD rather than redraw it natively in Revit, import the CAD detail in a separate revit file (NOT the main project file) to clean it up first such as removing CAD symbols, hatches, layers, and linestyles. Then copy/past or insert view.
    8. Remove old design options that are no longer needed. Revit has to consider each design option (even if turned off from view) and that can lead to slow model performance.
    9. Perform regular audits/compact the model when opening it. Daily or at least once a week.
    10. Reduce image sizes before importing
    11. Restart Revit to reset memory cache because Revit uses a lot of system RAM
    12. If possible, turn off Volume Calculations or set to calculate areas until needed.
    13. Don’t abuse groups. If something is very repetitive, consider creating families instead of grouping because they use less resources
    14. Don’t over-model families. If you need a highly detailed family, put the complex geometry on the highest detail level so it’s not normally seen, but can be turned on when you need it.
    15. Create a new central file occasionally if need be. Have all users exit out during this process and have users open up new central and obtain local copies of it when finished with the process.  Caution:  This destroys all backups of the central model.

    Consider the following best practices for managing views in your project.

    1. To improve performance when opening the project, set a drafting view with few if any elements as the starting view. See Specify the Starting View for a Model.
    2. Minimize view depth where possible in elevation, plan, and section views so that geometry hidden by other elements in the view does not affect the view drawing performance. See About the View Range.
    3. Consider back-clipping views to reduce the quantity of geometry maintained in a view. Often the overhead associated with additional object cutting due to back clipping is more than offset by the resulting reduced geometry maintenance. See Cut a Plan View at a Clip Plane.
    4. Use section boxes to limit visible geometry when working in a 3D view. See Change the Extents of a 3D View.
    5. Minimize the number of views in a project to reduce model size. Likewise, consider deleting as many views as possible from static models linked into the model.
    6. Use Wireframe or Shading display styles when working in a linked file environment. See Visual Styles.
    7. Avoid hiding large quantities of individual elements in views.
    8. Turn off unnecessary categories in Visibility/Graphics and templates. See About the Visibility and Graphic Display Dialog.
    9. When you use the Paste Aligned tool to closed views, target views will open and close. When repeating this several times, you can improve performance by opening all the target views before beginning the sequence of paste operations. Paste Aligned Elements.
    10. Zoom in to speed up drawing and snapping.
    11. If you have a dense view and snap lines appear to be shooting off in all directions, deselect the Snap to Remote Objects setting in the snap dialog. See Snaps Dialog.
    12. Close unnecessary views.
      • When working in a 3D view, most of the file is placed into RAM. These views should be closed when saving to central, because Revit will update this complex view as part of the save process.
      • Although Revit is optimized to update only views that are visible or become visible to the user, you can close hidden views to recover memory allocated to those views.
    13. Assign the proper level of visual detail to a given view. In a 1/8″ plan view, assigning a Fine level of display detail may be unnecessary. Plan views with fine and medium detail level are slow to open if there are many wall join layers to route. Use a Coarse view setting unless you need to show greater detail. See Specify the Detail Level for a View.
    14. Unless necessary, turn off shadows in views and before printing. See Display Sun and Shadows.
    15. Use the Draw visible elements only graphics setting to reduce the amount of information drawn during view navigation. This will also optimize the speed when panning, zooming, and orbiting the model. See Options Dialog: Graphics Tab.
