Java vs C Performance..
You might have discussed this topic many times and wondered which is better.
Is C/C++ faster than Java ? Well, it depends…
1) Platform independent
2) Garbage collection feature from JVM frees users from worrying about memory management.
3) Multi-threading /concurrency libraries
* C++ has smaller footprint.
*Very small startup time
*Direct machine access,
# On the fly code generation & execute. Its easy to execute same machine instructions on a simple RISC chip whereas Java needs JIT to do a good job with bytecodes.
# OS’s. These need lots of direct machine access (e.g. hardware interrupt support; page table support)
# Direct code generation with exact machine instructions will be generated from the C compiler. This is harder to do in Java because the translation layer is much more indirect.
