Speed Solutions for MongoDB View?

I created Mongo View from 2-5 collections`

    db.createCollection('myView', {
      viewOn: 'myColllection',
      pipeline: [
        {
          $lookup: {
            from: 'otherCollection',
            localField: 'otherId',
            foreignField: '_id',
            as: 'otherDoc',
          },
        },
        { $unwind: { path: '$otherDoc', preserveNullAndEmptyArrays: true } },
     ................

And then I try to compare GET DATA from View.aggregate() VS Collection.aggregate()

// 1
Collection.aggregate([.............])
// 2
MyView.aggregate([.............])

The result View.aggregate() is very slow than View.aggregate()
