NSTextAttachment lagging in textkit 2

I have an attributedString with 100 NSTextAttachments(contains image of 400kb). When i scroll the textview, it is lagging, When i did the same in textkit 1, it is butter smooth. It can be because of how textkit 1 & 2 layout the elements.

        let attachment = NSTextAttachment()
        attachment.image = UIImage(named: "image2")
        
        let attachmentString = NSAttributedString(attachment: attachment)
        let mutableAttributedString = NSMutableAttributedString(attributedString: textView.attributedText)

        for _ in 0...100 {
            mutableAttributedString.append(NSAttributedString(string: "\n"))
            mutableAttributedString.append(attachmentString)
            
        }

        textView.attributedText = mutableAttributedString

How to handle images in textkit 2 so that it feels smooth while scrolling textview?
