Jonathan, sound like it makes sense. In this case I think it is more important to size the external cache very well, instead of Solr's.
Even when 1/5th of the requests are redundant, an external cache could not answer the other 4/5ths and so decreasing Solr's cache would slow down the whole application. Since this is only a conceptual question, I really do not have got any benchmark - data. But if I have some, I will ask if it was possible to publish them.
