What version of OpenLayers are you using? WFS in 2.4 is greatly improved, and specifically, it only sends out one request, rathre than requesting in 'tiles'. I think upgrading to the latest version will actually be far more useful to you than using something older. If you are using 2.4, example HTML would be useful to help debug: perhaps there is something pathological in your dataset as well, so a link to the server might be useful, but I have a feeling just upgrading so that you're dealing with one request instead of 30 would be very useful.
