Is it worth trying MonetDB?

Question

Has anyone had any experience with MonetDB? Currently, I have a MySQL database that is growing too large, and queries are getting too slow. According to column-oriented paradigm, insertions will be slower (which I don't mind at all), but data retrieval becomes very fast. Do I stand a chance of getting more data retrieval performance just by switching to MonetDB? Is it MonetDB mature enough?
