JIT compiles the code on the end-user's machine, allowing it to optimise for the exact CPU that they are running. behaviour can vary due to other factors, such as garbage collection. I have heard that under certain circumstances, Java programs or rather parts of java programs are able to be executed faster than the "same". uhlstaedtersv.com › sites › quora › /05/26 › when-is-java-faster-than-c. As a rule of thumb, when you convert Java to C++, the code is about 3x slower. This doesn't make sense at first, until you consider that code. If my Java code is running, it will be faster than your C++ code. They write some code to do those tasks in each of at least two (and sometimes quite a few. uhlstaedtersv.com › Java › Languages and Runtimes. Loading Program Executable (LPE). Developers create new programs by writing code into one or more source files. A compiler/linker translates these source. - Use how to make java faster than c++ and enjoy Yet another "Java faster than C++" claim › Wander Lairson Costa
I never liked Java because I always thought it was quite verbose however, I never tried the new functional constructions in Java 8 and used to be very heavy. I mean, I could recognize that an app was written in Java in a blink of eyes, just by looking how slow it was. Back to the post, the code in question is a Huffman code implementation. You can find instructions on how install the Java code here. In this test, we are measuring the time to compress and decompress the sample mobydick. After a rough look at the source code, the heap allocations were quite suspicious, but after some experiments I realized this was not the case, then I started to profile the code. As I have no much experience on Mac development, and that includes native tools, I made some google research and came across Instruments. After some painful time trying to use it inside Xcode , I came back to google and found iprofiler. Instruments come with a set of Profiler templates , the one of interest here is the time profiler , which as its name says, profiles the time spent on function calls.
