Thanks Shawn. We will increase the JVM to 4GB and see how it performs.

Alexandre,
Our queries are simple (with strdist() function in almost all the queries).
No facets, or sorts.
But we do a lot of data loads. We index data a lot (several documents,
ranging from 10 - 100000 documents) and we upload data through out the day.
Basically, we are heavy on indexing and querying (simple queries) at the
same time.
