Troubleshoot Platform Performance Issues

When a project grows, some customers find that the platform feels slower than it did in the beginning.

Should you experience the platform getting slower or less responsive, while we are always happy to help via our support, here are some steps you can take on your own to try to speed things up again:

Cleaning up the Project

A project without unnecessary content is quicker to load and to display.

Number of Test Objects

Test Objects are always transferred alongside the project data. Depending on their size, they may have a huge impact on the amount of data that needs to be transferred (and stored in memory) when loading the project.

Recommendation: Especially review if some test objects are not needed anymore, because they are old, or you are currently working on different parts of your project, and delete those. Please refer to this guide on how to manage test objects.

Number of nodes

A huge number of nodes can also be bad for response times. Especially lookup tables, which create nodes that are invisible, can have a significant impact.

Recommendation: Keep your TRANSFORM area as clean as possible. Remove unnecessary or unused nodes and especially lookup tables.

Hide stuff you don’t need at the moment!

A huge number of Statements, combined with a lot of branches with a lot of containers take time to be displayed completely in your browser.

Recommendation: By collapsing the statements in the WRITE section, this rendering time can be greatly reduced. Please refer to this guide on how to collapse statements.

In the same way, moving nodes to subgraphs in the TRANSFORM section also reduces the time the graph needs to be diplayed and by that improves responsiveness.

Your computer

You can also help performance by making sure your own system performs well in the first place.

Your Browser

  • Is your browser up-to-date? (Chrome or Firefox work best for AX)
  • Are there a lot of open browser tabs? The number of open tabs (not only AX!) can overwhelm your system. Try to reduce that.
  • Do you run a lot of browser plugins? Browser plugins can have a huge impact on the performance. Refer to this article on performance impact of plugins for a list of the worst culprits. Be particularly careful with password managers or extensions that scan the content of every page like Ghostery, or Grammarly. You can test the impact of your plugins by opening AX Semantics in the private browsing mode of your browser, as that usually disables plugins, too.

Your Internet Connnection

Is your internet connection reliable and fast? You can check that on sites like

Your Computer

Is your computer up to the task? We recommend using AX Semantics on equipment that is able to handle large online applications. Helpful for that are reasonably modern CPUs and depending on the amount of tabs you want to open in your browser at least 4GB to 8GB of RAM.


The above tips mean to help you eliminate the most common reasons for lacking performance.
