Randall Leeds updated COUCHDB-890:
----------------------------------
Description:
Since COUCHDB-1075, there is a CommonJS module cache used for resolving
circular CommonJS dependencies. However, Caolan reports a 10x speed improvement
by not clearing this cache between requests. An option to not clear the cache
could be a great tool for performance-interested power users who know their
CommonJS modules are sane. The improvement will be even greater when we turn on
the JIT compiler in SpiderMonkey since cached modules will benefit from being
pre-JIT'd.
was:
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.
Summary: Option to use a persistent CommonJS module cache (was: Add
caching to CommonJS modules)
Updated in light of COUCHDB-1075 work.
