It seems you are trying to address multiple performance concerns at the same time. * Server side: the time it takes to return a set of features in response to a query * Client side: How long it takes to parse and draw them. In general, the latter is based entirely on the type of features: there is usually not a *significant* difference i parsing time between different formats of vector serialization once you've whittled the result set down to the IE6/IE7 limit of ~100 features. Once you've optimized the server side, investigating different options on the client side should be relatively simple, but pick one at a time and optimize.
