Flex big data volume performance (ADEP/LCDS dataservice)

As we have found a solution for Hibernate, server side loads the data very fast : less than a sec for thousands of records and more. Now the problem is on transporting data from server to browser. Two issue:

1.The datagrid always waits until the ArrayCollection is fully loaded. We overcame this by specifying :

<destination id="someAssemble">
    <properties>
        <use-transactions>true</use-transactions>
        <source>com.assembler.SomeAssembler</source>
        <scope>application</scope>
        <item-class>vo.SomeVo</item-class>
        <network>
            <paging enabled="true" pageSize="50" />
        </network>

==> the datagrid started display quickly. The problem is the server stops loading data from row 51. Is there a way to force Flex keep loading the data in the background (by config or by code )

2.If I try to load a big ArrayCollection (for example more than 20K records), it locks down the whole browser. Is it possible to load it smoothly behind the scene?

Please help! Thank you
