Vertxio Two: JMeter first blush

In Vertxio One we created our first Vertxio microservice.
Now lets "kick the tires". We are going to have your microservice serve up a 2 MB file per request.
We will use JMeter as the client and see *roughly* what the microservice can do.

Update Microservice:

	package vertxio.demo;
	import io.vertx.core.AbstractVerticle;

	public class MyDemo extends AbstractVerticle{

	public void start(){

	vertx.createHttpServer()
	.requestHandler( req -> {
	String file = "C:/temp/dummy.txt";
	req.response()
	.putHeader("content-type", "text/plain")
	.sendFile(file)
	.setStatusCode(200)
	.setStatusMessage("Sent: "+file);
	}).listen(8080);
	}
	}

Computer: Lenovo Laptop. Windows 7 64-bit. i5-3320M with 8GB ram.

JMETER Parameters:

300 users with a 600 second ramp up time.

JMETER results: (take results with a grain of sand knowing that I ran it in GUI &
graphing mode and didn't turn off other apps. This is just a ballpark to see what it initially yeilds.)

You can see that the throughput is 9,278 requests/minute. :)
The standard deviation is a touch higher than I would like. But again, this is first blush.

Vertxio One: Getting a Vertxio and Gradle up and running.

These the artifacts to get Vertxio3 up and running as a Gradle project.
I'm using Eclipse for the posting but you can use any environment you would like.
This will be an ongoing blog.

Vertxio One: Getting a Vertxio and Gradle up and running.
Vertxio Two: JMeter First Blush

1) You will need JAVA 8 and Vertxio 3.

2) Create a Gradle Project.

3) Edit gradle.build - copy and paste. Then add your class under the NOTE comment

	plugins {
	id 'java'
	id 'application'
	id 'com.github.johnrengelman.shadow' version '1.2.2'
	}

	dependencies {
	compile 'io.vertx:vertx-core:3.0.0'
	}

	repositories {
	mavenCentral()
	}

	//NOTE: Add your class here
	def mainVerticleDemo = "groovy:vertxio.demo.MyDemo"

	mainClassName = "io.vertx.core.Starter"
	run {
	args = ["run", mainVerticleDemo]
	}

	jar {
	manifest {
	attributes 'Main-Verticle': mainVerticleDemo
	}
	}

	shadowJar {
	classifier = 'fat'
	mergeServiceFiles {
	include 'META-INF/services/io.vertx.core.spi.VerticleFactory'
	}
	dependencies {
	exclude(dependency('io.vertx:codegen'))
	exclude(dependency('junit:junit'))
	exclude(dependency('org.mvel:mvel2'))
	exclude(dependency('log4j:log4j'))
	}
	}

4) Update dependencies

5) Create class that extends AbstractVerticle.

	package vertxio.demo;

	import io.vertx.core.AbstractVerticle;

	public class MyDemo extends AbstractVerticle{

	public void start(){
	vertx.createHttpServer()
	.requestHandler(req -> {
	req.response().putHeader("content-type", "text/html")
	.end("<html><body><h1>Hello from vert.x!</h1></body></html>");
	}).listen(8080);
	}
	}
