WordPress 6.1, scheduled for November 2022, will function a “large enchancment to database efficiency” because of new submit question caching.
This new function guarantees to make WordPress web sites carry out quicker.
The precise caching enchancment is to the submit question caching.
Within the Twitter thread announcement somebody requested if this enchancment was already launched in model 6.0.
They requested:
“Thanks! Wasn’t there an enchancment already in 6.0?
With that we had main points on large woo-stores: disappearing classes on archives pages when solely little one classes are checked, not the highest stage (mother or father) categorie.
Curious in regards to the be aware with extra context”
The WordPress core committer responded:
“We’re enhance database efficiency on a regular basis.
There was improved to time period question caching in 6.0. That is submit question caching. Associated however not the identical.
That challenge was patched in 6.0.1. I patched it myself.”
WordPress Database and Queries
WordPress shops numerous components of the web site in a database.
A database incorporates details about the positioning organized into tables.
For instance, the entire content material for webpage posts are saved in a desk.
When somebody visits a webpage, WordPress will “question” the database to go looking and discover the content material for that webpage within the database.
WordPress makes a number of queries to the database for each requested webpage and does it for each website customer.
Consequently that may grow to be a heavy load on a server when it occurs 1000’s of occasions per minute, leading to slower database efficiency which in flip slows down the complete website.
With this new database caching function, as a substitute of creating a database question it is going to as a substitute first verify if what it’s in search of is in a cache and pull the knowledge from there.
It’s analogous to putting an order for lunch and as a substitute of getting to attend for the lunch to be made, the order taker reaches beneath the counter and produces it immediately.
Huge Enchancment
In accordance with the WordPress core contributor who labored on this challenge, the caching function will lead to a dramatic enchancment.
The core contributor tweeted:
“In WordPress 6.1, there’s a large enchancment to database efficiency.
Database queries in WP_Query are actually cached. A ticket I’ve been engaged on for five+ years was merged.
This could lead to billions of much less repeated database queries”
A draft dev be aware was additionally begun containing extra details about the cache:
“WordPress 6.1 consists of an enchancment to how database queries are carried out within the ‘WP_Query’ class in order that the results of database queries will probably be cached in object caching.
Which means that if the identical database question is run greater than as soon as, the consequence will probably be loaded from cache.
For individuals who are utilizing persistent object caching, this may imply that till caches are invalidated, the database question won’t be run once more, leading to far few queries to the database.”
Response from the WordPress Neighborhood
The unofficial announcement was enthusiastically acquired.
Congrats. Such a big impact.

Final Minute Points Getting Fastened
Regardless of the enthusiastic tweet saying that this function will probably be within the subsequent WordPress launch, a final minute challenge arose that appeared to solid doubt on whether or not this function will make it into the subsequent WordPress launch.
The GitHub ticket for the cache challenge was closed, that means that every one the bugs gave the impression to be labored out and it was completed.
However hours later the identical WordPress contributor reopened the ticket as a result of new points have been found.
The issue that was found needed to do with persistent Object Caching.
They wrote an evidence:
“Reopening, as I’ve found a few points when persistent Object Caching.
Difficulty 1 – Cache add known as quite a bit when persistent Object Caching is enabled. It is because update_post_caches known as. This perform shouldn’t be known as when object cache is enabled.
Difficulty 2 – Cache set known as each WP_Query run, not solely the primary.”
A new GitHub pull launch was opened to doc the repair for the newly found points.
Confirmed: Database Cache Will Be in WordPress 6.1
I reached out to the developer by way of direct message on Twitter and he responded that there won’t be a delay.
He confirmed that as of right this moment there are six weeks left and these newly found points will probably be mounted and the brand new caching function will probably be included in WordPress 6.1.
Nothing has been formally introduced but however that’s commonplace. Each launch incorporates tons of of enhancements and an important are usually highlighted on the precise day of launch.
Count on the brand new function that can enhance WordPress efficiency to land in model 6.1, at the moment scheduled for November 2022.
