Hi everyone!

I've installed the tile server on a separate machine using SWITCH2OSM Manually building a tile server (14.04) and I've changed mapstyle to openstreetmap-carto. Everything works fine, but at 6-7-8 scales tile generation takes about couple of minutes.

I have used PostGIS Tuning, PG Tune, PG Tune Online, I have tried to use dozen of PostgreSQL configurations, but tile generation is not fast enough.

My hardware configuration is:

  • Intel(R) Xeon(R) CPU E5-2630 v2 @2.60GHz
  • 32GB RAM
  • SSD RAID-5

I thought it would be enough.

So the question is: "What is the best hardware solution for the tile server?". I want tile generation to take couple of seconds.

Thanks for help!

A couple of questions that may help people answer:

o How much data are you importing?

o Are you planning to update the data periodically?

Hello. 1. The whole world 2. May be once a year

What performance are you getting (at which zoom and which location), and what did you expect ?

I think it could be normal that the tiles for z6-8 take some significant amount of time to render, usually they are not rendered very often but only from time to time on demand. These zoom levels contain a big amount of data and are covering big areas so that the spatial index has less effect than in higher zoom levels.

You have to accept that tile generation on small zoom levels takes a couple of minutes, and pre-render these tiles in regular intervals. That's what OSM itself does too! The alternative is changing to vector tile technology altogether but then you'd have to re-generate the vector tiles in regular intervals which isn't much faster.

If his update schedule is "once a year", pre-generating shouldn't be a problem.

I have .meta files already, I don't work with .png itself. So, the only way to share not rendered tiles on 6-7-8 zoom levels is pre-render, right?

And it doesn't matter which hardware you have, anyway it will take couple of minutes, yes?

if you keep the whole database in memory it will speed rendering up a lot

Well, I guess you could get yourself one of these: https://www.oracle.com/engineered-systems/exalytics/features.html

But I don't think you envisioned needing to buy a new "house" when installing a new home tile server, because that is probably what a true professional business solution like this one is going to cost you...

Yeah, I guess so.

The only way is to pre-render tiles.

Where I can find how many GBs I must have to render the whole world on 11 zoom level? This table http://wiki.openstreetmap.org/wiki/Tile_disk_usage is not valid for meta-files. Thank you
