Java execution efficiency can be better than C / C
1. Everyone knows that now JVM has implemented JIT, a class is compiled into Native Code after the first run, and then a server runs for a while, the entire application may have compiled into binary code execution. .
2, C / C code can be able to run on the X386's compatible CPU, may not be able to use some of the Pentium's advantages, while JIT is different, can judge the current CPU type, compiled code may be compiled more than C / C Good efficiency
3. With the continuous improvement of JIT's algorithm, JIT can dynamically optimize the compiled code according to the execution of the last compiled code, making it compiled by the code efficiency, because the C / C compiler compiles Code of code.
In order to synthesize, we have reason to believe that Java's execution speed can be better than C / C .
