What's the difference between starting a Rails app with "trinidad" and starting it with "rails server trinidad"?

The difference is starting the server with rack handler (rackup -s trinidad) instead of booting it standalone (e.g. no runtime polling is going to be available while using the rack handler). You might inspect what happens when 'rack/hanler/trinidad' is required and what if the trinidad binary is executed ...

Thanks Kares

When I start my app with rails s trinidad things seem to work faster (both startup and refreshing a page) compared to when I start the same app with "trinidad"

Why would the different startups affect the performance?

It should not affect performance really that much ... of course it's observable for you when you boot things (since there's no 'additional' JRuby runtime boot to perform with `rackup`), but when things warm up it should be about the same (unless you run `trinidad` non threadsafe! with a pool - that might take longer to warm up and eat more memory + might handle less requests concurrently). If you do not need the Java/Rails integration bits that are setup with the standard ("non-rackup") way feel free to use `rackup -s trinidad`.
