What's causing the sudden increase in load times for Miro's presentation mode across all browser types?

Introduction

The sudden increase in load times for Miro's presentation mode across all browser types is a critical issue that demands immediate attention. This problem directly impacts user experience and could potentially lead to decreased engagement and customer satisfaction. In addressing this challenge, I'll employ a systematic approach to identify, validate, and resolve the root cause while considering both short-term fixes and long-term strategic implications.

Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking this might be a recent development. When exactly did you first notice the increase in load times?

Why it matters: Pinpointing the timeline helps narrow down potential causes and correlate with recent changes. Expected answer: Within the last week or two. Impact on approach: A sudden change suggests a recent trigger, while a gradual increase might indicate a systemic issue.

• Considering the cross-browser nature, I'm wondering about the extent of the problem. What's the average increase in load time we're seeing?

Why it matters: Quantifying the issue helps prioritize the response and set benchmarks for improvement. Expected answer: An increase of 3-5 seconds across browsers. Impact on approach: A significant increase might point to infrastructure issues, while a minor one could be related to content or caching.

• Given that it's affecting all browser types, I'm curious about our server infrastructure. Have there been any recent changes to our backend systems or CDN?

Why it matters: Server-side issues could explain the universal nature of the problem. Expected answer: No major changes, but we did update our CDN configuration last week. Impact on approach: Recent changes would be a primary focus, while no changes might shift focus to client-side issues.

• Thinking about user behavior, has there been any significant increase in concurrent users or complexity of presentations being loaded?

Why it matters: User behavior changes could strain the system in unexpected ways. Expected answer: We've seen a 20% increase in concurrent users over the past month. Impact on approach: A surge in usage might require scaling solutions, while stable usage would point to other factors.
