Slow field interaction when filling a form with Testwise generated controls

Hi,

I am using Testwise generated controls to create a purchase order. The test works, but filling the form feels quite slow.

Example code:

const expectedDescription = faker.person.firstName();
const purchaseOrderMain = await page.subject.PurchaseOrderMain;

await purchaseOrderMain.form1.descriptionField.fill(expectedDescription);
await purchaseOrderMain.form1.supplierIDLookup.lookupSelect('Demo supplier');
await page.getByTestId('form-field__delivery-date__date__input').fill('01/01/2027');
await purchaseOrderMain.form1.heatNoMandatoryCheckbox.check();
await purchaseOrderMain.toolbar482460FA.getSaveButton().click();

In the latest run, the purchase order was created as Purchase-0019. The form filling and saving part took roughly 35-40 seconds before the next step continued. I also see repeated warnings like:

Timeout reached while waiting for response. Proceeding anyway.

My question is about the slow interaction while filling the purchase order form.

Questions:

1. Is this delay expected when using generated form controls and lookup controls?
2. Is supplierIDLookup.lookupSelect('Demo supplier') known to wait for backend responses or metadata updates?
3. Is there a recommended best practice to make this faster or more stable?
