Blender is Slow
Reported by Chris Griego | July 22nd, 2008 @ 01:36 PM | in 1.2
The JavaScript-only blending of IAN can easily take 10s while skipping many files. That's a long time to lock up TextMate while waiting for for something to something to happen. Some profiling and benchmarking would help uncover the slow parts.
YUI Compressor might be to blame, which makes the do-not-compress option even more useful for development environments.

Does appear that YUI is to blame.
Boldpx (1 css, 2 js) * --min yui = 5.96772s * --min none = 0.00479s IAN prototype (18 js) * --min yui = 12.66291s * --min none = 0.38751sI'd still like to keep this ticket open to see what can be improved, but I'm bumping the milestone back since --min none makes this far less critical.

I have hunch that needs testing. YUI Compressor being slow is not something we can do a lot for, but the way we're currently using it means both Java and the YUI Compressor Jar is reloaded for each minified output file. Finding a way to initialize these only once and reuse would be one potential way to speed things up.

There's an existing feature request for YUI Compressor to be able to batch files from the command line, which the author does not seem interested in doing. What needs research is if we can batch within Blender by using some kind of Ruby to Java bindings.

Blender is like ant or make for the front-end. It aggregates and compresses CSS and/or JavaScript assets for a site into efficient, production-ready files.
