Now GA: Up to 20x Faster Pulumi Operations for Everyone

Thursday, Mar 5, 2026

In January, we introduced a major performance enhancement for Pulumi Cloud through a fundamental change to how Pulumi manages state that speeds up operations by up to 20x. After a staged rollout across many organizations, it is now enabled by default for every Pulumi Cloud operation. No opt-in required—just use Pulumi CLI v3.225.0+ with Pulumi Cloud. The improvement applies to pulumi up, pulumi destroy, and pulumi refresh; pulumi preview does not modify state, so it is unchanged.

Speeding up Pulumi Operations by up to 20x

Monday, Jan 12, 2026

Today we’re introducing an improvement that can speed up operations by up to 20x. At every operation, and at every step within an operation, pulumi saves a snapshot of your cloud infrastructure. This gives pulumi a current view of state even if something fails mid-operation, but it comes with a performance penalty for large stacks. Here’s how we fixed it.

Pulumi now handles secrets more efficiently through optimized encryption and decryption processes, reducing deployment times while maintaining security standards. Users of Pulumi Cloud for state management will notice the most improvement due to new batch API capabilities.

Benchmarking Python Performance

This is the second post in a series about performance optimizations we’ve made to the Pulumi CLI and SDKs. In this post, we’ll go deep on a performance improvement we made for Pulumi Python programs. You can read more about Amazing Performance in the first post in the series.

Achieving Amazing Performance in the Pulumi CLI

Thursday, Jan 26, 2023

This is the first post in a series about performance optimizations we’ve made to the Pulumi CLI. Over the last six months at Pulumi, the Platform Team has been working on a project we call “Amazing Performance.” Amazing Performance is a new initiative to improve the throughput and latency of the Pulumi CLI not only for power users but for everyone. By the end of June 2022, we assembled a list of issues containing both high-value improvements requiring a sizable investment and low-hanging fruit for quick wins. The full list, including the items we have yet to tackle, is contained in a tracking issue on GitHub. This blog series will cover the highlights.
