Why does a JRuby application on App Engine take so long to start?
- by Major Tom
I'm considering using JRuby on App Engine but have heard that Juby app on App Engine have a long startup lag. Why is this?
Is it because the JRuby jar files are so large that a cold startup requires them to be loaded into memory before the app can start serving?
That would be my guess but I'm not sure if that's a precise technical explanation.
