I tried some very basic tests with and without the resize option and it does seem to create a fair number of additional requests.
Here are my results... With Resize: Initial Load: 585 requests +1 Zoom level: 999 requests (+414 for the zoom) -1 Zoom level: 1096requests (+97 for the zoom) Without Resize: Initial Load: 419 requests +1 Zoom level: 683 requests (+192 for the zoom) -1 Zoom level: 731 requests (+48 for the zoom) The site I am testing with has about 5 WMS layers, a couple of vector layers (shouldn't matter) and about 15 tool buttons on the screen (plus the zoom bar, pan bar). On the initial load, there are 3 layers turned on. (If this info helps.....) For now, I will keep the resize effect turned off because it does seem to make a decent speed difference.
