 ### Loading...
 
-Often if the application is misconfigured the `Loading...` dialog is continuously displayed. This is most likely caused by the backed failing to start. The **Maintenance -> Logs** section should give you more details on what's happenning. If there is no exception, check the Portainer log, or start the container in the foreground (without the `-d` parameter) to observe any exceptions. It's advisable to enable `trace` or `debug`. Check the [Debug tips](./DEBUG_TIPS.md) on detailed instructions.

 ### Duplicate devices and notifications
 
-The app uses the MAC address as an unique identifier for devices. If a new MAC is detected a new device is added to the application and corresponding notifications are triggered. This means that if the MAC of an existing device changes, the device will be logged as a new device. You can usually prevent this from happenning by changing the device configuration (in Android, iOS, or Windows) for your network. See the [Random Macs](./RANDOM_MAC.md) guide for details.

+### Losing my settings and devices after an update
+
+If you lose your devices and/or settings after an update that means you don't have the `/app/db` and `/app/config` folders mapped to a permanent storage. That means every time you update these folders are re-created. Make sure you have the [volumes specified correctly](./DOCKER_COMPOSE.md) in your `docker-compose.yml` or run command.

+### The application is slow

+Slowness is usually caused by incorrect settings (the app might restart, so check the `app.log`), too many background processes (disable unnecessary scanners), too long scans (limit the number of scanned devices), too many disk operations, or some maintenance plugins might have failed. See the [Performance tips](./PERFORMANCE.md) docs for details.

-# Performance tips
+# Performance Optimization Guide
 
-The application runs regular maintenance and DB cleanup tasks. If these tasks fail, you might encounter performance issues. 
+There are several ways to improve the application's performance. The application has been tested on a range of devices, from a Raspberry Pi 4 to NAS and NUC systems. If you are running the application on a lower-end device, carefully fine-tune the performance settings to ensure an optimal user experience.
 
-Most performance issues are caused by a big database or large log files. Enabling unnecessary plugins will also lead to performance degradation. 
+## Common Causes of Slowness
 
-You can always check the size of your database and database tables under the Maintenance page. 
+Performance issues are usually caused by:
 
-![Db size check](./img/PERFORMANCE/db_size_check.png)
+- **Incorrect settings** – The app may restart unexpectedly. Check `app.log` under **Maintenance → Logs** for details.
+- **Too many background processes** – Disable unnecessary scanners.
+- **Long scan durations** – Limit the number of scanned devices.
+- **Excessive disk operations** – Optimize scanning and logging settings.
+- **Failed maintenance plugins** – Ensure maintenance tasks are running properly.
+
+The application performs regular maintenance and database cleanup. If these tasks fail, performance may degrade.
+
+### Database and Log File Size
+
+A large database or oversized log files can slow down performance. You can check database and table sizes on the **Maintenance** page.
+
+![DB size check](./img/PERFORMANCE/db_size_check.png)
 
 > [!NOTE]
-> For around 100 devices the database should be approximately `50MB` and none of the entries (rows) should exceed the value of `10 000` on a healthy system. These numbers will depend on your network activity and settings. 
+> - For **~100 devices**, the database should be around **50MB**.
+> - No table should exceed **10,000 rows** in a healthy system.
+> - These numbers vary based on network activity and settings.
 
-## Maintenance plugins
+---
 
-There are 2 plugins responsible for maintaining the overal health of the application. One is responsible for the database cleanup and one for other tasks, such as log cleanup. 
+## Maintenance Plugins
 
-### DB Cleanup (DBCLNP)
+Two plugins help maintain the application’s performance:
 
-The database cleanup plugin. Check details and related setting in the [DB Cleanup plugin docs](/front/plugins/db_cleanup/README.md). Make sure the plugin is not failing by checking the logs. Try changing the schedule `DBCLNP_RUN_SCHD` and the timeout `DBCLNP_RUN_TIMEOUT` (increase) if the plugin is failing to execute.
+### **1. Database Cleanup (DBCLNP)**
+- Responsible for database maintenance.
+- Check settings in the [DB Cleanup Plugin Docs](/front/plugins/db_cleanup/README.md).
+- Ensure it’s not failing by checking logs.
+- Adjust the schedule (`DBCLNP_RUN_SCHD`) and timeout (`DBCLNP_RUN_TIMEOUT`) if needed.
 
-### Maintenance (MAINT)
+### **2. Maintenance (MAINT)**
+- Handles log cleanup and other maintenance tasks.
+- Check settings in the [Maintenance Plugin Docs](/front/plugins/maintenance/README.md).
+- Ensure it’s running correctly by checking logs.
+- Adjust the schedule (`MAINT_RUN_SCHD`) and timeout (`MAINT_RUN_TIMEOUT`) if needed.
 
-The maintenance plugin. Check details and related setting in the [Maintenance plugin docs](/front/plugins/maintenance/README.md). Make sure the plugin is not failing by checking the logs. Try changing the schedule `MAINT_RUN_SCHD` and the timeout `MAINT_RUN_TIMEOUT` (increase) if the plugin is failing to execute.

-## Scan frequency and coverage
+## Scan Frequency and Coverage
 
-The more often you scan the networks the more resources, traffic and DB read/write cycles are executed. Especially on busy networks and lower end hardware, consider increasing scan intervals (`<PLUGIN>_RUN_SCHD`)  and timeouts (`<PLUGIN>_RUN_TIMEOUT`).
+Frequent scans increase resource usage, network traffic, and database read/write cycles.
 
-Also consider decreasing the scanned subnet, e.g. from `/16` to `/24` if need be.   
+### **Optimizations**
+- **Increase scan intervals** (`<PLUGIN>_RUN_SCHD`) on busy networks or low-end hardware.
+- **Extend scan timeouts** (`<PLUGIN>_RUN_TIMEOUT`) to prevent failures.
+- **Reduce the subnet size** – e.g., from `/16` to `/24` to lower scan loads.
 
-# Store temporary files in memory
+Some plugins have additional options to limit the number of scanned devices. If certain plugins take too long to complete, check if you can optimize scan times by selecting a scan range. 
+
+For example, the **ICMP plugin** allows you to specify a regular expression to scan only IPs that match a specific pattern.
+
+---
+
+## Storing Temporary Files in Memory
+
+On systems with slower I/O speeds, you can optimize performance by storing temporary files in memory. This primarily applies to the `/app/api` and `/app/log` folders.
+
+Using `tmpfs` reduces disk writes and improves performance. However, it should be **disabled** if persistent logs or API data storage are required.
+
+Below is an optimized `docker-compose.yml` snippet:
 
-You can also store temporary files in application memory (`/app/api` and `/app/log` folders). See highlighted lines `◀` below.
