Even leopard-webkit is quite laggy on my 1.5ghz G4 powerbook. It seems to me that three things slow webpages down: 1. interactive content 2. loading images 3. webpages with many resources on them, JS, CSS, Images, anything which triggers many more web requests. 4. (but already fixed with glimmerblock) ads It would be pretty easy to build extensions for TenFourFox to deal with these ^ problems and maybe such extensions already exist, but TenFourFox is painfully slow on my 1.5ghz G4 Powerbook. So I was wondering, are there mods of leopard-webkit out there which 1) proxy images through something to scale them down (or not load big ones at all), that 2) blocks <video> tags and <iframe> until you click on them, and 3) somehow reduces the amount of requests webpages require to load, perhaps by creating spritesheets on an external box, or merging resource files together. Opera used to have a service for mobile phones with not much data that did this. It was like a proxy where it would basically compress images down, and merge resource files together to reduce data, but this would also have the same effect of increasing performance.
