升级我的 DigitalOcean Droplet 后，我需要重建 Discourse 吗？

[merefield (Robert)]

You might want to consider at least quadrupling your:

UNICORN_WORKERS:

in app.yml and restarting the container …

as per:

@Stephen

I usually specify two unicorn_workers per core, and 25% of the system memory as db_shared_buffers

or you can run ./discourse-setup as per @pfaffman on that very same topic.
