[jira] [Commented] (BUILDR-658) Improve the speed of the all-in-one
package
[ https://issues.apache.org/jira/browse/BUILDR-658?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13764454#comment-13764454 ]
Tammo van Lessen commented on BUILDR-658:
-----------------------------------------
This is a great idea. If I understand correctly, this would render the all-in-one-package into a all-in-one-jarfile, right? This could also significantly lower the burden for new users since projects could ship with a mechanism (similar to gradle's) that provides a very slim code to download the all-in-one-package into an ignored folder and then launch buildr from there.

> Key: BUILDR-658
> URL: https://issues.apache.org/jira/browse/BUILDR-658
> Project: Buildr
> Issue Type: Bug
> Components: Packaging
> Affects Versions: 1.4.10
> Reporter: Peter Donald
> Assignee: Peter Donald
> Fix For: 1.4.13
>
>
> Running buildr under jruby is slow. A large portion of the blame can be attributed to rubygems and some can be attributed to the startup time of parsing the ruby files and the bytecode compilation under the JVM.
> It seems this is largely fixable by applying a few ugly hacks. These include;
> * Extracting all the ruby code into one directory. (Seems to show the biggest improvement)
> * Running jrubyc over the codebase and replacing all the .rb files with quires against the .class files such as warbler does
> In one project we applied these techniques and our startup time when from ~23s to ~1.5s however some projects see even better improvements. See [1] for a better explanation and some additional tricks to try.
