There are a few projects in the works to improve the experience for doing aggregation and analysis with data stored in MongoDB:

- Using V8 instead of spidermonkey [Will probably lead to better performance for MongoDB's map reduce] https://jira.mongodb.org/browse/SERVER-2407

- New aggregation framework [Will make it easy and fast to do simple aggregations] https://jira.mongodb.org/browse/SERVER-447

There is also Hadoop adapter that read and write directly from/to MongoDB that is in an early stage https://github.com/mongodb/mongo-hadoop

Switching to V8 seems like a red herring. Sounds like the current issues are with the architecture, not with the interpreter performance.

true to an extent (about performance), which is why I used the qualifier 'probably'. I should have said may instead! I think Eliot's comment sums it up pretty well: https://jira.mongodb.org/browse/SERVER-2407?focusedCommentId...

@rbranson - if you have thoughts on ways to improve, please do add them to http://jira.mongodb.org :)
