Getting a WordPress Website DoneImage CompressionNot difficult, but if you hold dozens or even hundreds of sub-sites, the situation has completely changed. This is no longer as simple as clicking the mouse, but a matter of life and death of the server "defense war". If the plug-in is not picked right, the background is light to turn around and lagging, heavy directly to the whole server strike.

for what reason?multi-siteWill the environment "turn off" common plug-ins?
Tools that work well in single-site environments tend to go on strike in multi-site environments. Behind this actually hides two people headache contradiction.
That said, these hundreds of sub-sites are all sharing the same "brain" - that is, your server resources. I've seen some webmasters delegate authority to sub-site administrators, resulting in more than a dozen people uploading high-resolution images at the same time and turn on compression. This time the server's CPU Occupancy will be instantly drawn out. This scene is no different from dozens of people crammed into a tiny kitchen frying at the same time, and in the end no one will be able to fire.

In addition to resource pressure, permission management is also a big trouble. As a super administrator, you have to act like a housekeeper, and find a balance between "delegating authority to sub-sites" and "unified management". Although some plug-ins are powerful, but it does not recognize the identity of the "network administrator". Do we have to open the backend of each of the hundred sub-sites just to change a setting? That's a nightmare for Ops.

What exactly are we looking at when picking a plugin?
In the face of the dazzling market of plug-ins, you may want to weigh these two core points before making a decision.
Must support network level one-click activation
When you install a plugin, make sure it supports "Network Activate". A good plugin will allow you to set it up once in the super admin backend and then automatically apply it to all sub-sites. You don't want to have to manually enter a hundred sites a hundred times! API keyRight?

Where exactly did the mission run?
This is something I value very much. With multisite networks, I prefer to "dump the pressure" on someone else.
In fact, everyone tries to pick the kind of thing that's incloud processingPlugins for images. If the compression task is running on the plugin side of the server, our main server is just responsible for sending and receiving files. This way, no matter how many new images the sub-site generates, odds are that it won't directly slow down access to the site.

Let's talk about some of the "old guys" I've used.
To help you save time in sifting through them, I've compared a few of the most dominant players on the market today.
Smush: A solid, old-fashioned choice
Many old webmasters will prefer Smush, its compatibility is really not to say, in the network background after a key to open basically do not care. Its batch compression function is particularly useful in dealing with those "old accounts". Although the free version of the volume of a single picture limit, but also enough to deal with the daily blog with pictures.

Imagify: Leave some room for image quality
If you're a fan of image clarity, you might want to try Imagify, whose interface logic is very clear and intuitive to use. Most importantly, its fault tolerance mechanism is well done. If any sub-site manager accidentally presses the image, you can still get it back quickly through backup. This kind of "regret medicine" is really necessary when managing a large network.

ShortPixel: Money-saving programs after the books are settled
When it comes to saving money, ShortPixel is probably the optimal solution for a multi-site environment. While many plugins charge per site, it allows you to buy a total quota and then share it between all your sub-sites. I've found this approach to be perfect for groups of sites that are updated with varying frequency. You don't need to pay individually for each small site that doesn't update for a long period of time, which inadvertently saves a ton of money.

Does everyone have a plan in mind now? Managing a multi-site network, choosing a plugin is actually choosing a way to save your mind.
Would you like me to help you recommend the best combination of plugins for your current server configuration?
