[jira] [Commented] (COUCHDB-890) Add caching to CommonJS modules

["Caolan McMahon (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/COUCHDB-890?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13028478#comment-13028478 ] 

Caolan McMahon commented on COUCHDB-890:
----------------------------------------

According to my tests this module caching patch doesn't actually work... the compiled function isn't available on the next resolveModule call and performance remains unchanged after the patch (when I've seen big speed improvements with the other implementation).

> We need some caching in the commonjs modules so that when you require('jsdom') it doesn't eval it every time you do a GET request to a show function.
> Patch coming.
