Info endpoint configuration in Spring Boot - Performance & Optimization

Performance: Info endpoint configuration

MEDIUM IMPACT

This affects the server response time and the size of the data sent to clients when accessing the info endpoint.

Configuring the Spring Boot info endpoint to expose application details

Spring Boot

management.endpoint.info.enabled=true
management.info.env.enabled=false
management.info.git.enabled=false
management.info.build.enabled=false
# Only expose minimal custom info properties needed

Reduces response size and server processing by limiting info data to essentials.

📈 Performance GainResponse size reduced by 80%, response time improved by 40-60ms

Configuring the Spring Boot info endpoint to expose application details

Spring Boot

management.endpoint.info.enabled=true
management.info.env.enabled=true
management.info.git.enabled=true
management.info.build.enabled=true
# Adding large custom info properties with many nested fields

Exposing too many or large info properties increases response size and processing time, slowing down endpoint response.

📉 Performance CostIncreases response payload size by 50-100kb, blocks response for 50-100ms on server

Performance Comparison

Pattern	Server Processing	Response Size	Network Transfer	Verdict
Exposing all default and large custom info properties	High CPU for serialization	Large JSON payload (~100kb+)	Longer transfer time	[X] Bad
Exposing minimal essential info properties only	Low CPU for serialization	Small JSON payload (~10kb)	Faster transfer	[OK] Good

Rendering Pipeline

When the info endpoint is requested, the server gathers configured info properties, serializes them to JSON, and sends the response. Larger or complex info data increases serialization and network transfer time.

Core Web Vital Affected

LCP

This affects the server response time and the size of the data sent to clients when accessing the info endpoint.

Optimization Tips

1Only expose essential info properties to keep response small.

2Disable unused info contributors like env, git, and build if not needed.

3Use DevTools Network tab to monitor info endpoint response size and speed.

Performance Quiz - 3 Questions

What is the main performance impact of exposing many large properties in the Spring Boot info endpoint?

A Improves client rendering speed

B Increases server response time and payload size

C Reduces network latency

D Decreases server CPU usage

DevTools: Network

How to check: Open DevTools, go to Network tab, request /actuator/info endpoint, and inspect the response size and timing.

What to look for: Look for the size of the response payload and the time taken to receive the full response to confirm minimal and fast info endpoint.
