In this release, search performance of different types of indices like single-tier (e.g. items only index) or multi-tier (e.g. 3-tier index having product-variant-item) has been further optimized. These optimizations also help to keep Elasticsearch clusters extremely cost-efficient by reducing the CPU and memory needed for them to scale.

By comparing performance between the initial 10.0 release and this release (10.0 HotFix 1), there is a performance improvement by up to factor 5 on an economical hardware setup for the Elasticsearch environment.

The following table illustrates the search response time examples tested for this release. Here are the parameters of the test setup:

Elasticsearch server is having 1 node of 8 CPUs and 32 GB RAM
3-tier search index example having a data volume of 4.8 million records (500k Products, 700k Variants, 3.5m Items)
Products, variants and items, all had complex data including attributes
The index held language-specific data as well

Results from the test scenario above:
