problem

• build, install, load도 느리지만,
• spring boot start가 제일 느리다.
  • 최고 800초를 넘는다.
  • 평균 500~600초

Cause

Try1.

spring.jpa.properties.hibernate.temp.use_jdbc_metadata_defaults=false 

Started MochaApplication in 469.81 seconds (JVM running for 475.449)

Try2.

chage db : mysql to h2

started MochaApplication in 466.076 seconds (JVM running for 471.271)

Try3.

1. host에 127을 추가하라는 글 (x)→ 이미 있음
2. plugin이 문제일 수 있다고 해서 안쓰는 플러그인 disable처리(x)
3. hibernate validator를 사용안함으로 설정하라는 글 (x)
   1. application.yml에 아래 설정 추가

    spring:
      jpa:
        properties:
          javax:
            persistence:
              validation:
                mode: none
   

4. start할때 before build옵션 제거
5. run java를 java8에서 java17로 변경 - 아주 약간 빨라짐

Try4. add java option

• disable launch optimization 추가
• disable jmx agent 옵션 추가

• result
  • as-is : 평균 550초
  • to-be: 평균 400초

Try5. change server (tomcat → undertow)

• pom.xml 변경

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
        <exclusions>
            <exclusion>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-tomcat</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
      
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-undertow</artifactId>
    </dependency>
  

• application.yml 변경

    server:
      undertow:
        threads:
          io: 8
          worker: 200
  

• result

  • 454 ~ 471초
  • 경량이라 기대했는데, 빨라지지 않음

Try6.

• spring.cloud.bus.autoconfigure.exclude 설정하고 lazyInit 적용

• bootstrap.yml

    spring:
      cloud:
        bus:
          autoconfigure:
            exclude:
