Re: All setting use cache
No, the problem is much worse in 1.0.x
Not only does the setting have no effect, 1.0 has a “reserved” option list which forces all foreign options (ie. set by plugins) to default to non-autoload, causing an extra query for each one unless they specifically add themselves to the auto-load list.
So other than hacking nearly every single existing plugin, you can try my workaround:
