Crystal looks really cool but if speed is what its after, i think it misses the target for most people.
because for most apps, you will be bottlenecked by the database server. it is the slowest hanging fruit on the tech stack, be it postgres , mysql, or mongo. so unless you are working on number crunching tasks that do not involve any db queries, i fail to see the benefit of a language like Crystal.
i wait for the day until the day Crystal becomes a 100% drop in replacement ready for Ruby apps.
until then, Sinatra is more than fast enough for most things.
