Embedded Database Performance Report

Actian Zen more than 6x faster than Couchbase

MCG Global Services Benchmark Results

September 2018

Key insights

This benchmark did a head-to-head comparison of Actian Zen Core and Couchbase Lite, both running on a Nokia 2, Android 7 handset (ARM-based) with 1GB DRAM

Actian Zen Core outperformed Couchbase Lite for Indexed and Non-Indexed data management by:

– more than 5x on inserts, up to 2x on deletes, and over 2x on updates

Actian Zen Core plus Actian Zen Edge was also faster as a client-server combination than Couchbase Lite plus Couchbase Sync Gateway plus Couchbase server, replicating IoT Device or Smartphone to gateway data sharing —the area where it tends to really matter in embedded Edge applications.
