DOMO and IBM Web Sphere Performance

We have a client that utilizes IBM Websphere to manage all of its employees' internet traffic. They currently connect to our site via SSO, and then we link them to a Domo App. We are currently using public embedded links to the Domo App.

We are seeing a significant impact on server performance when loading the Domo App. Sometimes, the data will never load, and the user will get an error message.

Has anyone had issues with IBM Websphere impacting performance?
