  • Different kinds of JIT compilers and how they work:

    1.  Econo JIT: Runs when the application is opened. This compiler has a very fast compilation time, but it produces un-optimized code - thus the program may start quickly but would run slow. This compiler is suitable for running scripts.

    2.  Standard JIT: Runs whenever the application is opened. This compiler has a somewhat slow compilation time, but it produces highly optimized code. Most of the time you would use this compiler to run your intermediate code.

    3.  Installation Time Compilation: This technique allows you to compile your application into native code at the time of installation on the computer. So the installation may take a few seconds/minutes more, but the code would run at speeds very close to a native C/C++ application.

    4.  Direct Compilation: Compiles source code directly into native code without any translation inbetween. This is ideal for applications that are to target only one platform, or are to target multiple versions of that platform. If it is to target more than one platform, the compiler would produce multiple output assemblies; each targeting one of those platforms.

  • Econo-JIT is obsolete now.
