On just about ever new deployment of ProjectWise I get the same question about Caching Servers.  “How do I know if I need a Caching Server in an office or not?”  Well, first we need to understand what a caching server does and a little more about how it will be used.

The ProjectWise Caching Server has a dual purpose.  The first is to store files that are managed by the ProjectWise system and the second is to cache files that are stored in remote offices.  A Caching Server generally would need the same processing power as a local file server and is not processor intensive. However, the addition of a Point Cloud Service can increase the need for processing power.  The Point Cloud Service is only needed on a ProjectWise Caching Server that is also the storage area for the point clouds.

For medium to larger installs, it is highly recommended that a ProjectWise Caching Server be at the same location as the ProjectWise Integration Server for performance reasons.  Having ProjectWise Caching Servers in a remote office is one of the largest decisions when determining the system architecture.  General rules for determining if an office needs a ProjectWise Caching Server include the following:

  • 10 or more users in an office that will utilize ProjectWise
  • Five or more users in an office that work on the same projects and files
  • Offices that have higher latency
  • Offices with limited bandwidth
  • Use of large files
  • When distributed storage is desired
  • When better performance is needed

In many offices that are right on the fence one way or another you may start with no Caching Server with the understanding if performance is an issue a Caching Server should be added.



I wanted to follow up on a previous blog about the Point Cloud Streaming that is now available with ProjectWise.  To start off with, the streaming is available for ProjectWise Clients running MicroStation, MicroStation based applications, Navigator, Descartes.  A future release will also include a connector for AutoCAD.

To give you a good feel for expected performance we ran some test on two Point Clouds. One, a relatively small 50 MB and the other was a 1.5 GB Point Cloud.  Not that our testing should represent the performance that you would experience, but it should give you a feel for what to expect.  Here are the results that we experienced:

Standard MicroStation Download and Launch:

  • 50 MB – 3 minutes 30 seconds
  • 1.5 GB – Greater than one hour

Streaming MicroStation Launch:

  • 50 MB – 1 minute and 26 seconds
  • 1.5 GB – 1 minute and 38 seconds
