115-121: Excellent addition to the documentation!The callout provides a clear and actionable suggestion for reducing workflow latency by increasing memory allocation. Specifying the recommended value of 512MB and comparing it to the default of 256MB helps users understand the potential performance improvement.
Increased memory allocation allows the workflow to handle more data in memory without needing to rely on slower disk I/O operations. It also provides more resources for compute-intensive tasks, resulting in faster execution times.
Referencing the troubleshooting section for additional performance optimization strategies is a great way to encourage users to explore other techniques and gain a deeper understanding of the platform.

249-260: Excellent addition of performance optimization tips!The new "How can my workflow run faster?" section provides clear and actionable advice for users to improve their workflow performance. The tips cover key areas like resource allocation, response handling, simplification, and cold starts.
The consistent formatting, helpful tone, and links to relevant documentation make these tips easy to understand and implement. Including this section in the troubleshooting guide is a great way to proactively address common performance issues.

298-305: LGTM!The informational callout provides a helpful tip for reducing workflow latency when handling HTTP requests. Returning a static response directly from the trigger configuration is an effective way to send the HTTP response immediately, without waiting for the remaining workflow steps to execute.
The reference to the "Sources" documentation is also useful for directing users to more detailed information on this topic.

|
||
| 1. **Increase Memory Allocation:** Increase your [workflow memory](/workflows/settings#memory) to at least 512 MB. Raising the memory limit will proportionally increase CPU resources, leading to improved performance and reduced latency. |

| 2. **Return Static HTTP Responses:** If your workflow is triggered by an HTTP source, return a [static HTTP response](/workflows/triggers#http-responses) directly from the trigger configuration. This ensures the HTTP response is sent to the caller immediately, before the rest of the workflow steps are executed. |

"Return Static HTTP Responses" -> "Return static HTTP responses". Generally we only capitalize the first words of these sections, or proper nouns or other Pipedream features, but see here how "static" and "responses" should be lowercase.

Change:
Use and increase the number of dedicated workers to eliminate cold starts, ensuring your workflow is ready to execute immediately.
to:
Use warm workers to reduce the startup time of workflows. Set as many warm workers as you want for high-volume traffic.

I would use the same terminology you do in the troubleshooting guide: "How can my workflow run faster?"

| To reduce latency from the trigger to the end of your workflow, consider increasing the memory allocation to at least 512MB. This will result in significantly better performance compared to the default 256MB. |
