slow it to .75 that made it almost possible to follow along lol

Thanks for the video. I have an issue in which my WMS request is taking 40 seconds to show the Layers on my front-end, I already set the storage for browser cache at 24 hours but every new first request from another machine takes 40 seconds, I tried every possible WebServer cache option and still doesn't work.

[@geospatialtechno]

Here are some suggestions for improving WMS request performance: 1. Check Server Load: Ensure the server isn’t overloaded. 2. Optimize WMS Configuration: - Use appropriate image formats (PNG vs. JPEG). - Optimize layer styles and queries for efficiency. 3. Review Network Latency: Test for delays between client and server. 4. Use Tile Caching: Implement a caching solution like GeoWebCache. 5. Database Performance: Optimize database queries and indexing. 6. Reduce Layer Complexity: Limit the number of layers or simplify geometries.

Good video, curious if its possibly to display the tiles as MVT?

[@geospatialtechno]

GeoServer can produce vector tiles in three formats: GeoJSON, TopoJSON, and MapBox Vector (MVT). These are also supported by OpenLayers and other clients. MVT is the preferred format for production.

Hello, thank you very much for the useful videos! question: I created a tile service in a geoserver with a coordinate for my country. The problem occurs when I add the wmts service to qgis, all maps are displayed except my map. I added my projection to qgis but it still doesn't show up

[@geospatialtechno]

Here are a few troubleshooting steps you can try to resolve the issue: * Check the Tile Layer URL: Make sure that the URL of your WMTS service in QGIS is correct and pointing to the correct layer in your GeoServer. * Check Layer Visibility: Ensure that the layer you added to GeoServer is set to be visible in the GeoServer layer settings. If the layer is not visible, it will not be displayed in QGIS. * Check Layer CRS: Make sure that the Coordinate Reference System (CRS) of your layer in GeoServer matches the CRS set in QGIS. If they do not match, the layer may not display correctly. * Clear the Cache: If you have made changes to the layer in GeoServer, try clearing the tile cache in QGIS to force it to reload the updated tiles. * Check for Errors: Check the logs in both GeoServer and QGIS for any error messages that may indicate what the issue is. This can help pinpoint the problem and guide your troubleshooting efforts. * Test with a Different Client: Try accessing the WMTS service from a different client or browser to see if the issue is specific to QGIS. This can help determine if the problem is with the service or with QGIS.

what is the difference should I feel when I use vector layer WMS and a vector layer added to geowebcash one ?

[@geospatialtechno]

Using a vector layer in WMS provides dynamic and up-to-date data but may result in slower performance, higher network traffic, and increased server load. Using a vector layer in GeoWebCache offers faster performance, reduced network traffic, and lower server load but may result in slightly outdated data because the data is pre-generated and stored in a cache on the server.

Thanks for your clarification
