Google reports why C++ is faster than Java

(Last Updated On: January 18, 2017)

I think this is the most compelling report yet coming from Google:

C was designed as an abstracted form of assembler.  The language was intended to allow the generation of very efficient native code.

In the decades since then, that intention has not changed.  C++ has optimising compilers that can infer the intent of the programmer, unroll loops, inline function calls, store temporary values in registers – and use SIMD instructions to execute multiple instructions in parallel.   C++ programmers (especially C++ games programmers) pore over the generated assembler and work out ways to squeeze every cycle of performance.

Google wrote a technical paper comparing the performance of different languages – in a set of regular, real life operations.

Most importantly is to eye the the graph that comes with this comment . Now you don;t have read or listen to those losers who ‘know’ everything

About caustic

Hi i there My name is Bryan Downing. I am part of a company called QuantLabs.Net This is specifically a company with a high profile blog about technology, trading, financial, investment, quant, etc. It posts things on how to do job interviews with large companies like Morgan Stanley, Bloomberg, Citibank, and IBM. It also posts different unique tips and tricks on Java, C++, or C programming. It posts about different techniques in learning about Matlab and building models or strategies. There is a lot here if you are into venturing into the financial world like quant or technical analysis. It also discusses the future generation of trading and programming Specialties: C++, Java, C#, Matlab, quant, models, strategies, technical analysis, linux, windows P.S. I have been known to be the worst typist. Do not be offended by it as I like to bang stuff out and put priorty of what I do over typing. Maybe one day I can get a full time copy editor to help out. Do note I prefer videos as they are much easier to produce so check out my many video at youtube.com/quantlabs
