Hi There,
When i was going through the examples i noticed that "control.js" and
"extras-control.js" being added to UI and i dont think this script is
minified. does this affect the performance in anyway? or its okay to
have it as it is?
Click does not minify these scripts at runtime if thats what you mean. A
minified script can save a bit of bandwidth though. For example running
control.js through JSmin saves up to 40%. So control.js shrinks from 10kb to 6kb.
However if you use the PerformanceFilter, JavaScript and CSS files will be
gzipped and a far future expiry header set so they are cached in the browser,
and are only downloaded once.
To answer your original question is a bit hard because it depends on how much
traffic the site will have. But for the average site I would say, yes it affects
bandwidth but I don't think you need to worry about it, especially if Click is
fronted with PerformanceFilter.
Btw I believe the bigger performance gain to be had is not in minifying the
scripts but rather combining the scripts into one. Since browsers by default
only make two connections at a time, the more resources to be downloaded the
slower the site loads.
If you are not already using it I suggest you look at YSlow, its quite a useful
tool to grade your site performance.
kind regards
