JPAContainer Performance

Vaadin 6 / 7 / 8 Framework Data Binding

I used JPAContainer and wrote a simple application to display the data in a DB table. Its performance is very bad. Every time, I scroll up/down it takes several minutes to load the data. There are no much data in the that table (around 100 records).

The code looks like this:

        InitialContext ic = new InitialContext();
        CmsConfigProviderBean cmsConfigProvider =  (CmsConfigProviderBean) ic.lookup("java:module/CmsConfigProviderBean");
    	JPAContainer<CmsConfig> cmsConfigContainer = new JPAContainer<CmsConfig>(CmsConfig.class);
        cmsConfigContainer.setEntityProvider(cmsConfigProvider);
        Table listTable = new Table();
    	listTable.setContainerDataSource(cmsConfigContainer);

        VerticalLayout layout = new VerticalLayout();
        layout.setSizeFull();

        layout.addComponent(listTable);
        getMainWindow().setContent(layout);

When I switch to SQLContainer, the performance is back to normal.

Should I apply any special configuration to make it perform better?
