How can I improve the performance of Rails partials?

To improve the performance of Rails partials, consider using fragment caching, minimizing the number of partials, and avoiding complex logic within them.

What is fragment caching and how does it work?

Fragment caching allows you to cache the output of a partial so that it doesn't need to be re-rendered on every request. You can use it by wrapping your partial in a cache block.

Are there any tools or gems that can help with this?

Yes, gems like 'dalli' for Memcached or 'redis-rails' for Redis can help manage caching effectively in your Rails application.

What are some common mistakes to avoid when using partials?

Common mistakes include overusing partials for small components, not caching effectively, and including too much logic in the partials themselves.
