+## Make Yazi even faster than fast
+
+While Yazi is already fast, there is still plenty of room for optimization for specific users or under certain conditions:
+
+- For users who don't need image previews at all, disabling the default `image` previewer and preloader will make Yazi faster by reducing the I/O read file and CPU decode image consumption.
+- For users managing network files, it's recommended to disable all previewers and preloaders since previewing and preloading these files means they need to be downloaded locally.
+- For low-spec devices like Raspberry Pi, [reducing the concurrency](/docs/configuration/yazi#tasks) will make Yazi faster since the default configuration is optimized for PCs, and high concurrency on these low-spec devices may have the opposite effect.
+- For users who don't need accurate mime-type, [`mime.yazi`](https://github.com/DreamMaoMao/mime.yazi) may be useful, as it simply returns mime-type based on file extensions, while Yazi defaults to obtaining mime-type based on file content for accuracy. Mime-type is used for matching opening, previewing, rendering rules. Encourage users to choose the appropriate `mime` plugin based on their needs, which is why we decided to open it up to plugin developers.
