Not much information to go on… Start with elimination – disable the plugins, switch to default (or better – blank) theme. If it gets better – just find code at fault. If you are down to the bare and clean WP core and still having the issue – likely you have some server configuration issue. … Read more
Theme template files are organized in this way because of the WordPress Template Hierarchy. Since all primary template files eventually fallback to index.php, it is certainly possible to use only the index.php primary template file. There are advantages and disadvantages to using either method. Generally speaking, the usefulness/efficiency of defining template files is inversely proportional … Read more
I’ve actually been in the exact situation you’re in before, all you need to do is drop the __()s and the _e()s and replace them with their first parameter, you can pretty easily do this by regex if there are a lot, and it’s quick to do by hand if there aren’t…I’m not sure what … Read more
You can’t “optimize” Jetpack. Look at the URL; it’s served from wordpress.com. You get what they offer from their servers.

Many pages were a problem when your permalink structure was a plain /%postname%/, because that is the same structure the post type page is using. Very complex additional rewrite rules were stored in the database to avoid collisions. This is not a problem anymore. If your permalink structure is the same for posts and pages, … Read more
The performance of WordPress does not depend on the number of posts. It depends on the server performance (how fast can PHP scripts be executed). And the performance of the MySQL Server. The server performance is normally no problem if you got enough memory. The bottleneck is in most cases the MySQL server and the … Read more
There is no performance difference, because the result of get_bloginfo() comes from an internal cache anyway, because most (all?) of the return values come from get_option() calls, and these are cached internally with wp_cache_set() and fetched with wp_cache_get(). See Exploring the WordPress Cache API. Even if there would be a difference it would be too … Read more
You seem to be a little confused about what function APCu performs. It only implements key/value store. It performs no opcode caching, since the whole point of APCu is to leave that to new Zend implementation of opcode. When you use APC(u) and compatible object cache plugin WP switches to storing its cache (which is … Read more
