Is there any way to improve the application load time in Protractor?

The initial application load time of an angular application for e2e testing using Protractor is consuming a longer time. Is there any way to improve this?

The page object used for initial login is :

var Login = function() {
var username = element(by.model('login.username'));
var pass = element(by.model('login.userpwd'));
var loginButton = element(by.xpath('//*  @id="logindiv"]/div[3]/div);

this.login = function(name, password) {
     browser.get(config.loginUrl);
     username.sendKeys(name);'
     pass.sendKeys(password);
     loginButton.click();
  };
};
module.exports = Login;`
