Spring boot eureka server taking up too much CPU and RAM

Question

I am using following pom.xml for my Eureka Server and running in a standalone mode with around 300+ services are being registered on it.

            </plugin>
        </plugins>
    </build>

</project>

application.properties for the service :

spring.application.name=service-registry
server.port=8080
eureka.client.register-with-eureka = false
eureka.client.fetch-registry =false
eureka.client.serviceUrl.defaultZone:http://IP:8080/eureka

Dockerfile :

FROM openjdk:8
WORKDIR /
ADD /target/*.jar service-registry.jar
ADD configuration/application.properties configuration/application.properties
ADD configuration/logback.xml configuration/logback.xml
EXPOSE 8080
ENTRYPOINT ["java","-jar","service-registry.jar"]

When I start/restart eureka service then it takes up around 35-40% of the entire CPU available and memory consumption keeps on increasing continuously. After keeping the service ON for say ~2 days it takes up all memory which has been allocated right now.( ~1Gb) Is there any way to reduce the memory or cpu consumption for eureka server ?
