<p>No - there isn't yet a discussion. I just learned about it today from Martin Dobias, that the SQL expression compiler is one of the major issues. I asked Nyall and Martin to look into the issue, why the rendering is so slow with many rules.</p>
<p>Feel free to discuss it publically on the developer list.</p>
