Ruby’s EventMachine – Part 2 : Asynchronous != Faster | Big Fast Blog

Ruby’s EventMachine: Asynchronous != Faster #ruby #rails #nodejs #node #developer ** VPS ->

I will gladly take a little overhead and fire up a new process or a new machine, if necessary, if it means that an external service like Memcached will not bring my event-loop to a halt when it has issues. It may be fast now, but one network glitch or Memcached crash may render my event-loop defunct. I might go from processing 10k requests per second to processing 1 per second, if I have a timeout of 1 second on one blocking network connection. So, yes, I will gladly suck up this asynchronous overhead in the short-term to protect from [expected] unexpected issues in the future.
