Let's try this way: we had many users requesting us to add a new option to set l2-cache-size=100%, but we never agreed on a good API. Patch (1) would do precisely that (l2-cache-size=1T). Patch (2) changes the default, which may be better and probably enough for many users, but it's not what solves the problem. Berto
