#2"This is a sweet spot for MongoDB." Made my day.
Full disclosure -- We've been locking horns with them for a while now, so of course this feels good.

#3Couchbase, the nodejs of databases. Everything is async. Want indexes updated, async. Want replication, async. Want commiting stuff to disk, async.
When you try to sync stuff (indexes + disk-commit) the performance will take a hit.

#4TLDR: MongoDB benchmarked Couchbase Server by having it perform CAS operations (read + update) while MongoDB performed basic operations (update), they used an outdated client library that is two years old, and they performed it with single node deployments.

Many applications find sync writes to replica memory on other rack(s) to be a good substitute for sync to disk. The disk sync can be batched every second or so for higher throughput and your application is safe. Where this really plays out well is when the disk goes slow for a minute (cloud-style) and the database stays fast.

MongoDB showing that in the years since this[1] was published that have learned nothing. Still chasing artificial benchmarks at the expensive of data safety and either personal or corporate integrity.

#8I did not see a link to the independent benchmarks that was referenced here. Does anyone have the link?
I would be interested in seeing the actual results and summary of it.

Good catch. Fixed.
