Writing software program that works below excessive load is an artwork that requires lots of ability, whatever the programming expertise that’s getting used.
Java platform is a perfect option to create large and complicated software program techniques as a result of Java is the preferred programming language, it has the biggest expertise pool, and its options, instruments, libraries, and group round it supplies for the very best improvement productiveness.
There may be an excessive amount of the criticism about Java efficiency that yow will discover on the internet. However, as quite a few academy researches had proven, the efficiency of the software program code strongly relies on the talents of the authors who had carried out the code and far much less it relies on the expertise that was used for its implementation.
In fact, every expertise has its sturdy and weak factors.
For instance, picture and video processing, numerical simulations, physics and different simply vectorizable floating level computations are particularly performance-sensitive and get a major efficiency increase from being carried out on the lowest attainable degree all the way down to meeting.
There’s a lot financial sense in these areas to choose extra low-level, much less productive and fewer developer-friendly implementation expertise.
Nevertheless, it seems that fashionable Java VMs obtain the identical efficiency as native languages like C and C++ for a lot of real-life enterprise duties that require excessive efficiency, so you may have a cake and eat it, too.
Many of the methods, approaches, and patterns which are getting used within the extremely loaded software program techniques observe from the frequent sense and from the deep understanding of the fashionable server-side CPU architectures. Nevertheless, sure high-level options of the Java platform that make it simpler and extra productive for software program builders, make it additionally more durable to write down high-performance code.
Builders want to grasp the way in which during which Java objects are specified by reminiscence, the algorithm of the rubbish collector, the peculiarities of the just-in-time compiler within the JVM, and different particulars to be able to take them under consideration through the design of their software program to realize the excessive efficiency of the ensuing code.
The discuss that will likely be made throughout Oracle JavaOne 2013 convention will information the listener although all these Java-specific points. The discuss is predicated on the real-life expertise of the dxFeed venture – the pure Java market knowledge vendor.
It has proved that cautious consideration to particulars and aware implementation permits one to supply a pure Java system whose useful and non-functional parameters are on par or exceed the extra conventional approaches, whereas making it simple to combine the ensuing answer with enterprise monetary techniques that are written principally in Java.
The same discuss was already offered throughout a latest Java Person Group occasion in St. Petersburg, Russia.
The video from the discuss (in Russian) might be discovered right here whereas the slides (in English) are right here .
