javascript - Would it benefit to pre-compile jade templates on production in express -

when using jade-lang on production, benefit having form of middleware pre-compiles .jade views , uses them in res.render? or automatically happen when node_env=production?

i'm exploring options on how speed-up jade rendering on production.

when jade compiles template, template cached. in production environment if warm cache, there no need pre-compile template. if don't, template cached after first compilation.

i recommend have jade's source code better understand how works.

exports.render = function(str, options, fn){   // ...   var path = options.filename;   var tmpl = options.cache     ? exports.cache[path] || (exports.cache[path] = exports.compile(str, options))     : exports.compile(str, options);   return tmpl(options); };

exports.renderfile = function(path, options, fn){   // ...   options.filename = path;   var str = options.cache     ? exports.cache[key] || (exports.cache[key] = fs.readfilesync(path, 'utf8'))     : fs.readfilesync(path, 'utf8');   return exports.render(str, options); };
