Script Preparation code:

var posts = {};
for (var i = 0; i < 10000; i++) {
    posts[i] = {
        id: i,
        content: "test posts " + i,
        commentsCount: 1,
        comments: {
            meta: {
                total: 1,
            },
            list: [{
                content: "just a comment"
            }]
        }
    }
}
