It emphasizes on expression evaluation instead of command execution. Wikipedia When did it all start In the 90s, there was a war between declarative programming and imperative programming. Declarative programming then represented by logic programming languages like Prolog and early functional languages like Erlang. And imperative languages were r... |

Writing correct programs is hard; writing correct concurrent programs is harder. Java Concurrency in Practice. So, why bother with concurrency? A number of reasons: Concurrency provides a natural method for composing asynchronous code. Concurrency allows your program to avoid blocking user operations. Concurrency provides one of the easiest ways take advantage of multi core systems. As processor counts increase, exploiting concurrency will be an even more important facet of high performance systems. |

tl;dr "Transparent Hugepages" is a Linux kernel feature intended to improve performance by making more efficient use of your processor's memory-mapping hardware. It is enabled ("enabled=always") by default in most Linux distributions. Transparent Hugepages gives some applications a small performance improvement (~ 10% at best, 0-3% more typically), but can cause significant performance problems, or even apparent memory leaks at worst. To avoid these problems, you should set enabled=madvise on your server... |
