In this comment in SERVER-9135, I see that indexes (other than the _id index) should now be built in parallel during initial sync.
However, in testing with 3.0.5 I see that all indexes on a collection are built sequentially. Furthermore the speed of each index build is CPU-bound on a single CPU core.
mongod log file from repro attached.
