The parsing plays a major role and is already the bottleneck in the app.

When using the app, the more the number of comments a post has, the longer it takes. On older devices (iPhone 6S or cheaper Android phones for example), it can take 10-15 seconds to parse 500 comment posts. My app already has to take this into account and therefore only displays 20 comments right away and then adds additional comments as it's finishing parsing the rest.

Since the app has a "go to next top level comment thread" button, this button has to stay hidden until all 500 comments have been parsed. So any slowness in the parsing can significantly ruin the experience.
