Great post btw. I am looking forward to getting some production apps onto 2.1 in the coming weeks and seeing how performance characteristics have changed in the new release.
- tmm1 13y agoWe implement preload_all, which loops over app/{models,controllers}/ and requires everything. This method is generally called from config.ru, and happens in the unicorn master before it forks off workers. I recently upstreamed a warmup method for Rack::Builder you can also use for this purpose: https://github.com/rack/rack/pull/617 https://github.com/rack/rack/pull/617
- venus 13y agoThanks for that link (and for submitting it!). I've done something similar in deploy scripts, to warm up a fresh instance before bringing it into rotation - even better having it able to be baked into rack like that.
- purephase 13y agoThat's interesting. Thanks for sharing. I'll have to check this out.
