MongoDB的简单QPS测试（单机）

mongoDB官方网站下载：

1、mongodb-linux-i686-2.2.1.tgz

2、java驱动 mongo-2.2.jar

 

 测试服务器为Dell  E5410 的Debian linux 2.6，配置为：

1、4核，2.33GHz

2、内存3G

3、SATA硬盘2T

 

 web服务器：tomcat5.5

打压工具：Apache Bench

监控工具：mongostat

 

测试思路：

1、因为MongoDB内置了连接池，所以客户端程序相对简单，只需从一个Mongo的单例获取连接即可；

2、每个请求做1000次插入；

 

测试代码MongoDBManager：

public class MongoDBManager {
static private MongoDBManager instance; // 唯一实例
//public static final String DB_NAME = "lab";
//  public static final String MESSAGE_COLLECTION = "email";   

static synchronized public  MongoDBManager getInstance(final String ip, int port, int poolSize) throws UnknownHostException {
if (instance == null) {
instance = new MongoDBManager(ip,port,poolSize);
}
return instance;
}

private MongoDBManager() {
}

private MongoDBManager(final String ip, int port, int poolSize) throws UnknownHostException {
init(ip,port,poolSize);
}

public DB getDB(String dbname) {
return mongo.getDB(dbname);
}

private Mongo mongo;

public void init(final String ip, int port, int poolSize)
throws java.net.UnknownHostException {
System.setProperty("MONGO.POOLSIZE", String.valueOf(poolSize));
if (mongo == null) {
MongoOptions options = new MongoOptions();
options.autoConnectRetry = true;
options.connectionsPerHost = poolSize;

ServerAddress serverAddress = new ServerAddress(ip, port);
mongo = new Mongo(serverAddress, options);
}
}
}

 

 测试代码InsertMongodbServlet：

public class InsertMongodbServlet extends HttpServlet {
public void doGet(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
Integer insertNum = Integer.valueOf(req.getParameter("insertNum")
.toString());
resp.setContentType("text/html;charset=UTF-8");
resp.setHeader("Cache-Control", "no-cache");

DB db = MongoDBManager.getInstance("127.0.0.1", 27017, 500)
.getDB("lab");

DBCollection tests = db.getCollection("tests");
for (int i = 0; i < insertNum; i++) {
DBObject test = new BasicDBObject();
test.put("id", 10000);
test.put("name", "This is for mongodb insert.");
tests.insert(test);
}

resp.getWriter().write(" Insert mongodb successed!");
}

public void doPost(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
}
}

 

开始压力测试，开1000个线程，共插入100万条记录： 

/usr/sbin/ab -n 1000 -c 400  http://192.168.175.130:8080/labWeb/insertMongodb.do?insertNum=1000

 监控：bin/mongostat

 可以看到在400个并发情况下，插入100万记录，QPS在28000左右。
