i don't understand - Couchbase took 1ms per operation without durability configured, ie. in memory. What took so long? Or is network roundtrip included?
>However, MongoDB implements a single lock per database (link). MongoDB nodes are limited to executing a single write at a time per database.
that sounds like a nightmare. Are they for real?
Looking at the results - durable configs, MongoDB and DataStax, have 3ms latency with 25K and 75K ops/sec. Are they using HDDs or SSDs? As a reference point - 5 years ago I was hitting 3.5ms on 15K disks on Oracle, at 20-30K ops/second (durable).

priceless.
