"And that startup time of JVM is orders of magnitude worse than pretty much anything else."
Sure, let's throw out of the window all the optimizations the VM can do at runtime because it takes a whole second to start the VM.
And you need to actually compile the source file before executing it!
Those server applications should all be written in bash because it's instantaneous!
Kidding aside, one prof at my university once told me that she wished students should still have to compile and wait for a program to start. When there is such a delay, it pays to read your code and try to understand it before running it (as opposed to run-and-see-what-happens).
