Types of JIT Compilers

When the program is executed the CLR activates JIT compiler ,inturn this JIT converts the MSIL Code (Non Executable) to Native Code(Executable) on demand basis as each part of Program is needed

Types Of JIT Compilers are as stated below :
(1) PRE JIT

(2) ECONO JIT

(3) NORMALE JIT


(1) PRE JIT : It Compiles complete source code to native caode In a single Compilation.

(2) ECONO JIT : It compiles only those methods that are called at Runtime.

(3) NORMALE JIT : It compiles only those methods that are called at Runtime and are stored in cache.When these methods called again they retrieve from cache.
