If there’s one thing that I despise, it’s when sites move slowly. Like they drag. And when it comes to blogging software, these usually are hella draggers. But fortunately there are a few ways to speed things up without actually giving up as much. The biggest one that you can ever focus on is caching.
Caching basically means that instead of telling the server to dynamically process something, it has a statically saved copy somewhere that it basically reads off. That shaves ticks off the seconds when you don’t have to ask the CPU to figure out what some variable is saying. And with most database driven applications, there are two methods to do this.
DB Cache: This is less well known but is actually an entirely brilliant design. Basically, it makes the assumption that you’re going to be querying your database a lot, and thus it saves those queries statically and can shave off seconds for you if you have large queries to make. This basically means that it’ll be slow the first time around, but not so much the next if you happen to repeat things a lot. Very useful in that sense.
WP Super Cache: WP-Super Cache is one of the most well-known in the WordPress community. It allows you to cache the pages themselves after the first time they’re built into static calls. This means that instead of reading directly from the database and generating the page, it creates the page the first time and doesn’t change out that copy until there’s a new one to change with. This basically allows the first person to read it to have a bit of slowness, but after that the page is already kept around.
As you can see, there are at least two different caching methods that you can implement to improve the quality and decrease the time latency. And in the web world, time latency is everything.
