Revit slow performance

Issue:

Slow performance when working in Revit.

Causes:

Working in a Revit model involves interacting with many systems, and if any one (or more) of those systems have slow performance, the entire experience in Revit can be slowed down.

At a high level, there are the following systems:
  • The Revit software.
  • Supporting software (for example, Microsoft .NET Framework, Visual C++ Redistributable).
  • Third party software and services (that are running at the same time as Revit taking resources away from the system and potentially directly interfering with the program).
  • The storage media (slow performance reading or writing to the storage media will slow down operations that do this).
  • The operating system (OS updates can influence Revit performance).
  • The system hardware (including CPU, Graphics Card, RAM...).
Important points to keep in mind when looking at performance issues:
  • If the performance recently changed, what (if any) of the items above were changed?
  • What are you comparing the performance against? (For example, if a new system appears to be slower than an older system, review the journals of both systems when going through similar steps to look for differences as well as comparing the specifications between the systems).

Solution:

Initial items to check

  1. Check that Revit is updated.
  2. For files hosted on a network or cloud location, save a local copy and retest (to identify if the issue is with the model, or the remote resource).
  3. If there are linked models, test unloading the links, to identify if the links are related to the slow performance.
  4. Disable add-ons to identify if they are related to the slow performance: How to disable add-ons for Revit
