title: Max number of goroutines
body: <p>How many goroutines can I use painless? For example wikipedia says, in Erlang 20 million processes can be created without degrading performance.</p>
  
  <p><strong>Update:</strong> I've just <a href="http://en.munknex.net/2011/12/golang-goroutines-performance.html" rel="noreferrer">investigated in goroutines performance</a> a little and got such a results:</p>
  
  <ul>
  <li>It looks like goroutine lifetime is more then calculating sqrt() 1000 times ( ~45µs for me ), the only limitation is memory</li>
  <li>Goroutine costs 4 — 4.5 KB</li>
  </ul>
