[mapserver-users] mapcache for website tips

[Sebastiano Laini]

Hi all,

I'm curious to know what are your mapcache configurations for a use in a website.

I'm using tiles of 128x128 and the maximum weight of a single tile can be 80KB, our map is counting 33 layers and a total of 60GB of data (whole UK EPSG:27700, Ireland is just the border and a white background). On first load with OpenLayer 4 and preload infinity (Preload. Load low-resolution tiles up to preload levels. 0 means no preloading) I load around 350 tiles and the load times is around 8 second (if the zoom layer is cached)

I'm also seeding with metatile 4 4 that was the old standard used before I changed the tilesize, which are the best settings I should use for web (tile size and which should be the max file size) and seed caching? As you know in previous posts I'm having really big issue in seeding the whole projection and I'm trying to figure out how to improve the service. (bear in mind that we update the data 2 at year so I need to recache again every 6 months)
