Puma is the web server shipped with Mastodon[2] and recommended by the Heroku hosting provider as a replacement for Unicorn.[3]
Deliveroo published a benchmark comparing the two servers and concluded “Puma performs better than Unicorn in all tests that were either heavily IO-bound or that interleaved IO and CPU work”, but that Unicorn was still slightly better performing in situations where CPU load was the limiting factor.[4]
