I am writing a WordPress shortcodes plugin for a client and admittedly don’t know much about load times. Which would load faster, one enqueued script with a size of 300kb or 10 separate enqueued scripts with a total size of 150kb (about 30kb each)?
So another way to ask this question would be, ‘does it take a noticeable amount of time to enqueue a script in WordPress?’
Enqueuing is not the bottleneck, the HTTP overhead is it. Combine and minify those scripts. Make sure they are compressed.
