WordPress Website Performance Optimization Guide_php Tips
1. Choose a good host
Try not to use free hosting or shared hosting (Godaddy, Bluehost, etc., so-called unlimited bandwidth, unlimited websites, etc.)
First of all, it is best for your domain name and your host to be in the same IDC. If not, it is recommended that you use a DNS service provider with a good reputation so that the domain name can be resolved to the host as quickly as possible. This is not the point, the point is yours. The server/host space should be fast enough, how can it be fast? CPU configuration, CPU usage, physical memory size, disk type and disk I/O performance (including the disk used by the Mysql database server), Mysql response speed and the number of Mysql concurrency, etc., will all affect the speed of the website. , and it is a physical influence.
2. Choose a faster theme
What kind of theme can be faster? Intuitively, themes that contain as few php, js, css, and font (font or icon font) files as possible will perform better. From a code perspective, a theme that is well coded and loads the right files on the right page will be better.
3. Choose a caching plug-in
It is recommended to use W3 Total Cache or WP Super Cache, both are free, but both are easy to use. I personally prefer W3 Total Cache because it supports: page caching, HTML compression, object caching, database caching, client Browser caching, and CDN.
4. Use a CDN
For overseas users, CloudFlare is good; for domestic users, Accelerator is good.
5. Enable Gzip
If the server supports it, enable Gzip. The above-mentioned caching plug-in W3 Total Cache allows you to enable this.
6. Use well-coded plugins
WordPress has countless plug-ins, but not all plug-in codes are well-coded, which requires you to determine which plug-ins are suitable for you. The most intuitive way is: when you install a plug-in with less than 3 stars from the WordPress plug-in directory, you should carefully understand its code! How to know?
7. Pay attention to updating your themes and plug-ins in time
Updating the WordPress themes and plug-ins you use in a timely manner can not only improve the security of your WordPress website, but some updates are targeted at performance, which will improve performance.
8. Optimize the database
You can use plug-ins such as WP-Optimize or WP-DBManager to optimize your database. These plug-ins can delete unmoderated spam comments, articles in the recycle bin, and automatically saved drafts or articles. Rollback version etc. Of course, the best way is to access your database and execute SQL statements to perform these operations yourself, if you feel you are familiar enough with both SQL and WordPress.
9. Optimize uploaded images
For any website, pictures are an important element on the page, but the size of your picture must match the size of the largest container you use this picture in, rather than the original P one Just upload a picture or photo directly. For example: you want to upload a picture. The maximum width of the container where this picture is located is 948px, and the width of the picture itself is 1600px. You should process this picture so that its maximum width is 948px. This can significantly improve the loading speed of the web page where the image is located, shorten the loading time and save server resources and bandwidth.
Another situation is: the maximum width of the image you upload is the same as the width of the largest container you use to modify the image. In this case, it is recommended that you use Smush.it and the WordPress plug-in based on it to process the uploaded image. For pictures, of course, you can also use desktop software like Lossless Picture Compression Master (picture compression software is recommended) or online websites like jpegmini to compress your pictures.
