Is JIT Slower?

Hi Group,
Here is my thought
This is rarely the case. The overhead associated with JITing a few methods is minor compared to the time spent reading in a few pages from disk, and methods are JITed only as they are needed. The time spent in the JIT is so minor that it is almost never noticeable, and once a method has been JITed, you never incur the cost for that method
As mentioned above, the version1 (v1) JIT does most of the optimizations that a compiler does, and will only get faster in the next version (vNext), as more advanced optimizations are added. More importantly, the JIT can perform some optimizations that a regular compiler can't, such a CPU-specific optimizations and cache tuning.
Cheers Anand |
