Why has JFrog Artifactory's download speed decreased by 30% over the past week?

Introduction

JFrog Artifactory's download speed decrease of 30% over the past week is a critical issue that demands immediate attention. This performance degradation directly impacts user experience and could potentially affect our customer retention and acquisition rates. I'll approach this problem systematically, focusing on identifying the root cause, validating hypotheses, and developing both short-term fixes and long-term solutions.

Clarifying Questions (3 minutes)

• Given the sudden drop, I'm thinking there might have been a recent deployment or configuration change. Has there been any significant update to Artifactory or its infrastructure in the past 1-2 weeks?

Why it matters: Recent changes often correlate with performance issues. Expected answer: Yes, there was a minor update to the caching system. Impact on approach: If confirmed, we'd focus on the caching system first.

• Considering the 30% decrease, I'm wondering if this affects all users equally. Are we seeing this slowdown across all regions and user types, or is it concentrated in specific areas?

Why it matters: Helps narrow down potential infrastructure or CDN issues. Expected answer: The slowdown is more pronounced in certain regions. Impact on approach: We'd investigate regional CDN performance and network routes.

• Looking at the timing, I'm thinking about potential changes in usage patterns. Have we seen any significant shifts in the types or sizes of artifacts being downloaded recently?

Why it matters: Changes in usage patterns could strain the system differently. Expected answer: There's been an increase in large binary downloads. Impact on approach: We'd focus on optimizing large file transfers and storage systems.

• Considering external factors, I'm curious about our current system load. Has there been a substantial increase in the number of users or download requests compared to previous weeks?

Why it matters: Increased load could explain performance degradation. Expected answer: User numbers are stable, but download frequency has increased. Impact on approach: We'd look into scaling our infrastructure and improving request handling.
