Slow Episerver Form Performance with Marketing Connector Integration

  • Updated

Here are several possible reasons why your forms may be slow when used with Marketing Automation Integration. 

  1. The site is not on a high enough Forms version. It should at least be on the following. 
    EPiServer.ConnectForMarketingAutomation 4.2.0. The below should also be updated.

    EPiServer.MarketingAutomationIntegration.X (where X is a connector such as Saleforce)

    For Marketo update to at least the following versions(latest as of 4/16/2018):
    EPiServer.ConnectForMarketingAutomation 4.4.2
    EPiServer.MarketingAutomationIntegrationIntegration.Marketo 3.2.1
    EPiServer.Marketing.Automation.Forms 1.4.2

    If Salesforce is used, then that package needs to be updated instead of the Marketo one(preferably to the latest version).


  1. The new caching settings have not been properly implemented. See the following:
    MAI Caching

  2. More than one MAI connector is used. For instance if Pardot and Salesforce integration connectors are used, performance will be very slow. 

  3. Xforms are used instead of the new forms. Xforms do not take advantage of the caching changes made in the first step.

  4. If you are noticing slower performance after an upgrading forms you may need to adjust a custom view. Check to see if a custom view is used for displaying the selection element blocks. Episerver.Forms 4.9.1 introduced a change to the view so the same change needs to be replicated in your custom view. Here is the default code(only for 4.9.1) you can use if using a customization. 

  5. If you do not require auto-fill, the feature can be turned off.
