The Snowflake Performance Index (SPI) is an aggregate index for measuring improvements in Snowflake performance experienced by customers over time. The SPI is calculated based on a comparable cohort of stable customer workloads consisting of millions of jobs each month.

Overview
Snowflake constantly innovates on performance with the goal to reduce customer cost over time. Regular performance improvements to the platform are a proven track record of putting customers first.
Many performance improvements occur behind the scenes, and are often applied automatically.
Snowflake uses real customer data to drive performance features, not fictitious or synthetic benchmarks. The SPI shows improvement on actual customer workloads.

*Measured by the Snowflake Performance Index (SPI), which tracks comparable, stable workloads (query count, spend and data processed). Query duration was measured over the 24 months preceding April 30, 2026. Improvement was influenced by factors including infrastructure, software enhancements and customer optimizations.

"We are able to have large-scale data processing all within the Snowflake environment, giving us greater agility and speed at a lower cost. With Snowflake as the central data storage and Snowpark compute, we've reduced data movement costs."
