As a result of investigating SERVER-676 we discovered that simply batching bulk inserts at the end revealed a significant increase in performance during index builds.
Right now inserts are performed 1-by-1, incurring the overhead of an entire WriteUnitOfWork for it. As we saw with BatchedDeletes, batching would alleviate the overhead.
The very rough patch attached here yielded an approximate 10% improvement in throughput.
