How to reduce MongoDB size after remove data

[Aroxo Senraj]

1. First I have checked MongoDB Size 36GB

2. I have removed few tables data

3. Again I have checked MongoDB Size (36GB) not reduced. After I have searched google and solution. 

I have tried few below methods and take more time, slow my application (hang)

Method 1: db.repairDatabase

Method 2:

db.getMongo().getDBNames().forEach(function(dbName) {

    if ("local" != dbName && "admin" != dbName && "system" != dbName) {

        var subject = db.getSiblingDB(dbName);

        subject.getCollectionNames().forEach(function (collectionName) {

            print('Compacting: ' +dbName + " - " + collectionName);

            subject.runCommand({ compact: collectionName });

        });

    }

});

So, I need better solution. If any one know about this kindly let me know.
