I've been playing around a bit with the browser config a bit and I don't think the default config is caching pages the way it's configured. I've enabled caching of previous pages (up to 5) and set the disk cache at 16mb and I think it's improved browsing speed.
If somebody could do some more testing, it might be of interest. I can't tell which config it's reading as there are two, so I've edited both.
after mounting rw
DiskCacheTotalBytes=1MB (or 16MB in browser-app.conf)
DiskCacheLargestObjectSize=500k (or 1MB in browser-app.conf)
In both files. Mount ro and reboot. You should notice that the pages when you hit Back load a bit faster. Sites such as reddit will display the previous content, not completely reload the page. Is this working for anybody else or is it just my mind?
