nailgun

问题 I'm try to use Nailgun on Debian GNU/Linux 9 (stretch) . "Nailgun is a client, protocol, and server for running Java programs from the command line without incurring the JVM startup overhead. Programs run in the server (which is implemented in Java), and are triggered by the client (written in C), which handles all I/O." Some documentation found: Nailgun Quick Start JVM Startup Times/Nailgun How to improve performance of java using nailgun server DSpace/Nailgun I use Oracle Java version 10.0

问题 When running Jython programs through nailgun the jython program always runs with the command line arguments of the first time it was run. first I start nailgun: arthur@a:~/nailgun$ java -jar nailgun.jar NGServer started on all interfaces, port 2113. then when I run a simple jython script: import sys print sys.argv then add jython to nailguns classpath ./ng ng-cp /usr/share/java/jython.jar then run the script with the word "first" as an arguemnt: arthur@a:~/nailgun$ ./ng org.python.util.jython

问题 I installed JRuby 1.7.2 in RVM, created a gemset, executed bundle install. Now, I run this: Term 1: [lzap@lzapx my_app]$ bundle exec jruby --ng-serv NGServer started on all interfaces, port 2113. Term 2: [lzap@lzapx my_app]$ JRUBY_OPTS="--1.9 --ng" bundle exec rails s The issue is nothing happens, on both sides the terminals do not print anything, it just hangs forever. Top does not show any java/jruby processes working. If I try to start the application without --ng, it works okay. What is

问题 I have just set up Nailgun (https://github.com/martylamb/nailgun, http://martiansoftware.com/nailgun/), which is a clever piece of kit which makes the JVM hang around in memory making Java and Jython (potentially) launch more quickly. This is great for Java, but it promises to be absolute gold dust for me for Jython, particularly during development (Jython is the best language in the world, but has a slow start-up time). Googling to see whether anyone had tackled running Nailgun on Eclipse I

问题 Every now and then I think it would be nice to use clojure for shell scripts , but a startup time of about 900ms is way too slow. I'd then google startpage for "nailgun clojure", but the only results that show up are for special cases like vimclojure. That's when I, pretending not to have time, turn to more awk ward languages that start up faster. So, how can nailgun be used to speed up the startup time of clojure? 回答1: Debian Do the following once: apt-get install nailgun # install nailgun
