Upgrade please to http2 for speed (30-40% faster response)
Is there a way to cache hole country before start server in redis?

ARolek commented 3 years ago

@adriantabirta

I believe Go's http package automatically supports HTTP2. The key is supplying an SSL cert in your tegola config. Take a look at: https://github.com/go-spatial/tegola/tree/v0.13.x/server#config-properties
Yes, you can use the tegola cache seed command. The doc formatting looks a bit off, but here's an overview: https://tegola.io/documentation/cache-seeding-and-purging/. You will want to use the --bounds command to inform the seeder what area you want to seed.

@ARolek Thanks.

It runs but, for zoom <8 it loads very slow or never (tested localy). Is there any option to raster tiles?

ARolek commented 3 years ago

@adriantabirta I would need a lot more context. Usually when tiles are taking a long time to process there could be serverl culprets

Do you have spatial indexes setup?
Have you optimized your configuration to reduce the amount of attributes necessary per feature?
Have you optimized your layer filtering? i.e. don't show all data at all zooms.
Have you done any simplification of your geometries? Especially important on lower zooms.
What data provider are you using (PostGIS / GeoPackage)?

It would be great to get some of this into the docs. ;-)

@ARolek wow, a lot of thinks to know, I just use PostGIS and try to build a POC iOS app using MapBox iOS SDK, it runs but slow, zoom I use 0-20 for all. Also not all data is displayed (street numbers, green area, lakes...) Would be nice if you have 30 min to talk on a call (just to figure out what I am doing wrong and help me to optimize server PLEASE).

@ARolek

Do you have spatial indexes setup? - yes
Have you optimized your configuration to reduce the amount of attributes necessary per feature? - donno
Have you optimized your layer filtering? i.e. don't show all data at all zooms. - I will do this 👍
Have you done any simplification of your geometries? Especially important on lower zooms.- Don't know how 😞
What data provider are you using (PostGIS / GeoPackage)? - PostGIS, exported using imposm3

ARolek commented 3 years ago

@adriantabirta what version of Postgres / PostGIS are you using? You would probably see some performance gains from using ST_AsMVT: https://github.com/go-spatial/tegola/tree/v0.13.x/mvtprovider/postgis

@adriantabirta I'm closing this issue for now, but if you need additional help feel free to re-open it.
