wp_register_script() just adds an entry to an array, it doesn’t do anything resource intensive. See WP_Dependencies::add(). Registering scripts early helps to avoid collisions, so you should do that always on wp_loaded.
Depends. One argument could be that if the requested page use all sizes then there will be a lot of image calls (slower response, bandwidth etc) but you can bypass that i.e. by loading images with JS. Also more sizes means more disk space usage. I don’t think there is any significant performance concern related … Read more
This is not the normal behaviour of WordPress. As others have mentioned it could be JS render blocking as the Database has already finished grabbing the data and displaying. I would first investigate your browser console and see what its returning on the network tab and if the console has any 404s as a broken … Read more
The templates are, by definition, the mechanism to define how a certain woocommerce page would look, and child themes are, by definition, the way you change a behavior of a theme beyond what it allows for in the Admin UI. Overriding the templates in a child theme is the best practice. (Bear in mind that … Read more
WP options (which is one of the most basic and used storage APIs) can be stored with or without “autoload” setting. Usually this is reasonable, since many options will be checked on each and every page load, so loading them in bulk during core load is much more efficient than individually. Problems usually start when … Read more
Your site appears to be pretty well structured in most ways and you’re getting a good score. If you’re seeing a huge swing day to day, test to test, etc, then it’s probably a hosting related issue. What type of hosting are you on? Is it cloud, is it shared, is it WordPress specific? https://developers.google.com/speed/pagespeed/insights/?url=http%3A%2F%2Fwww.greenstuff.sk%2F&tab=desktop … Read more
It would depend on the speed of the NFS and the speed of the local network. If your using an object cache like APC the plugins and theme file folders will not be effected because they will be loaded in memory. A better solution would be to use a CDN or even create your own … Read more
This is much more complex than looking up string versus integer. WordPress sifts permalink through a set of persistent regexp-based rules. And it affects logic a lot that string might be many more things than number. See one of better writeups on topic for details. Practical point to know – this doesn’t concern most sites, … Read more
Any time your traffic goes up your CPU usage will go up. Based on what you’re saying it could be bot activity. I’m also assuming you’re on a shared host that is overloading the server with 10 billion accounts. My suggestions include: Running a virus scan for WordPress via any number of available plugins Minimize … Read more
“squat” is synonymous with “nothing” in this case. So, I’d say: Before you consider using nginx, be aware that PHP APC or a similar opcode cache with a WordPress caching plugin is going to offer significant performance improvements over just switching from Apache to nginx. If you aren’t already using a PHP opcode cache and … Read more
