There are lags on page re-fetching

[Aichnerc]

Describe the bug
When the refetching is called:

this.intel.appendList(sources).then(() => {
  platformData = { ...this.getData(), user };
  this.session.tasks.user
    .cache(JSON.stringify(platformData))
    .then(() => {
      fetchedUser.platformData = platformData;
      this.setState({
        fetchedUser,
      });
    });
});

The page becomes laggy for about 10 seconds. No text can be selected and no actions can be made by the user.

To Reproduce
Steps to reproduce the behavior:

1. Login
2. Experience

Expected behavior
The page should run as smooth as Mr. Proppers baldness.
