Anyone else find Safari going really slow recently (last month or so) and then speeds up when you reboot the iPad or clear down the cache. Happening all the time and getting annoying. Any thoughts?

No, I've never had it slow down enough that I've given any thought to clearing the cache.

In all humility, one might suggest that it might have more to do with the sites you are visiting, unless you know them well enough that you are able to discount that possibility.
