Web page loading acceleration

EL-jos

Hey, everybody,
I'm developing a web browser.
Here's my simple code:

#include "controleur.h"
#include <QWebEngineProfile>
#include <QWebEngineSettings>

Controleur::Controleur(QWidget *parent) :
    QWidget(parent)
{
    setupUi(this);

    page = new QWebEngineView(this);
    page->settings()->setAttribute(QWebEngineSettings::AllowRunningInsecureContent,true);

    page->setGeometry(0,0,750,350);
    page->load(QUrl("https://www.google.com"));

    connect(page,&QWebEngineView::loadFinished,this,&Controleur::on_loadFinished);
    connect(page,&QWebEngineView::loadProgress,this,&Controleur::on_loadProgress);
    connect(page,&QWebEngineView::loadStarted,this,&Controleur::on_loadStarted);

    page->show();

}

void Controleur::on_loadFinished(bool ok)
{
    status->setText(" Chargement de la page terminée.");
}

void Controleur::on_loadProgress(int progress)
{
    bar->setValue(progress);
}

void Controleur::on_loadStarted()
{
    status->setText(" Nouvelle charge de la page est démarrée.");
}

void Controleur::on_precedent_clicked()
{
    page->page()->triggerAction(QWebEnginePage::Back);
}

void Controleur::on_actual_clicked()
{
    page->page()->triggerAction(QWebEnginePage::Reload);
}

void Controleur::on_suivant_clicked()
{
    page->page()->triggerAction(QWebEnginePage::Forward);
}

my problem is, I can't understand why my browser is really slow.
it can even take 3 minutes to load the page and even after the signal finished(), I have to wait at least 1 minute to be able to click on the link or something else on the page.
so I'd like to know how I can speed up the loading of my browser?

Thanks in advance for your help

@EL-jos are you sure your connection is not slow?

I mean, have you tried with a different browser on same machine?

what about running this minimal example?
