TopJ

Performance Test

Spring Boot v3.3.4

Preamble

For this test we'll focus on the org.springframework package and we are using openjdk version "21.0.8" 2025-07-15 on Linux

Test Class

We are using the following code to test throughput latencies using the stress test tool ab with 10 threads and a total of 1000 GET requests that return a 200 page with "Hello, World". More complicated annotation beans could be tested but for now we'll stick to core vanilla.

ab -n 1000 -c 10 http://localhost:8080/

The command line with problematic packages omitted is:

java -javaagent:TopJ.jar=3,100,'^(?=.*springframework)(?!.*(ConcurrentReferenceHashMap|java.util.|org\.springframework\.core\.env\.SystemEnvironmentPropertySource|org\.springframework.core\.env\.MapPropertySource|org\.springframework\.core\.MethodParameter|org\.springframework\.util\.LinkedMultiValueMap|BeanPostProcessor|org\.springframework\.boot\.util\.LambdaSafe)).*$',err -jar spring-boot-0.0.1-SNAPSHOT.jar

Results

This is the situation after all 1000 requests have been processed (cut at 0.05ms min avg for brevity):

This is ApacheBench, Version 2.3 <$Revision: 1879490 $> Copyright 1996 Adam Twiss, Zeus Technology Ltd, http://www.zeustech.net/ Licensed to The Apache Software Foundation, http://www.apache.org/ Benchmarking localhost (be patient) Completed 100 requests Completed 200 requests Completed 300 requests Completed 400 requests Completed 500 requests Completed 600 requests Completed 700 requests Completed 800 requests Completed 900 requests Completed 1000 requests Finished 1000 requests Server Software: Server Hostname: localhost Server Port: 8080 Document Path: / Document Length: 12 bytes Concurrency Level: 10 Time taken for tests: 7.999 seconds Complete requests: 1000 Failed requests: 0 Total transferred: 150000 bytes HTML transferred: 12000 bytes Requests per second: 125.01 [#/sec] (mean) Time per request: 79.992 [ms] (mean) Time per request: 7.999 [ms] (mean, across all concurrent requests) Transfer rate: 18.31 [Kbytes/sec] received Connection Times (ms) min mean[+/-sd] median max Connect: 0 0 0.5 0 6 Processing: 7 50 105.3 42 3278 Waiting: 7 44 104.8 36 3270 Total: 7 50 105.3 42 3278 Percentage of the requests served within a certain time (ms) 50% 42 66% 52 75% 61 80% 65 90% 80 95% 98 98% 117 99% 137 100% 3278 (longest request)

The initial finding are that there no serious bottlenecks anywhere. All methods are generally fast. The max does skew the stats - for example org.springframework.boot.loader.net.protocol.jar.Handler.assertInnerUrlIsNotMalformed: max=112.63 ms, total=112.72 ms, avg=3.22 ms, calls=35, but this is likely an inner JVM JIT thing outside the scope of this. You can see where the requests have an impact on stack by seeing the number calls that are >1000.

Solution

With no major bottlenecks of note, it's hard to fault this popular microservice. The only fix suggested is to limit the amount of classes and method calls - the stack is extremely fragmented, and method calls amounting to millions can add drag.
