Re: OSM Tile servers

Lynn Deffenbaugh

Yes, I've had a rendering server running for over 2 years now. Entire planetary database, updated every hour from OSM data.

My server runs in a Ubuntu VMWare VM on my Windows server.  The VM has access to 6 cores, 6GB RAM, and 5 SSDs totalling 1.5TB of space distributed over several logical volume manager volumes with various database tables on each volume to distribute the I/O load.  The smallest SSD (111GB) is dedicated to holding the flatnodes file (for those that are familiar with OSM tile rendering servers).

So, the rendering is slow because it's not a screaming machine nor does it have access to loads of RAM (the server only has 24GB), but the biggest bottleneck is my outbound Internet bandwidth.  I've got 25.7Mbps down, but only 6.44Mbps up (just measured at

Oh, and I recently moved my Ethereum test and main network clients into that VM.  Parity and geth are much more stable under Ubuntu than they were under Windoze.

If you want to see the munin performance graphs of the tile server, check out the following URL:

If you want to download large areas of tiles for offline use, you can
set up a Configure / Map / Tile Set pointing to my current OSM tile
server.  It's slow, but it'll eventually deliver your tiles.

It seems you have set complete rendering server, not just cache?
