My two cents. Rethink the application design.

In general WFS layers are a really bad idea. Do everything on the server 
that you possibly can.  With WFS you are slowed by large network data 
traffic and more importantly, the limitations of javascript compared to 
whatever the server is running. You want to use WMS layers to maximize 
speed and use WFS for queries.
See maybe 
http://lists.osgeo.org/pipermail/openlayers-users/2012-February/023918.html
(use a spatial bbox filter instead).

Note also, a very useful function that I think isnt documented well:
OpenLayers.Protocol.WFS.fromWMSLayer(layer)
Ie create layer as a WMS layer and this function returns a wfs protocol 
object for it that you can use for querying.
