Recommended specs

Recommended specs for running the mapserver

Storage

The tiles are cached in several zoom-levels on disk. Storage usage depends heavily on map-size and explored areas but it will be in the region of several gigabytes (5 to 10 GB for "older" servers)

Memory

Memory depedends on the amount of caching (see: Configuration) Per default there will be around 500 mapblocks cached for quicker access. This will be around 5 to 10 megabytes depending on the contents.

The recommendation is to maximize caching so the queries don't slow down the game-database. If you are willing to spend around 2 GB of memory set the maxitems to 5000 mapblocks. Otherwise leave the defaults and see if it has any impact.

Example config from mapserver.json:

{
        "mapblockaccessor": {
                "expiretime": "10s",
                "purgetime": "15s",
                "maxitems": 500
        }
}

CPU

The application is more CPU-bound than IO-bound. It will use all the configured CPU's while rendering:

It is recommended to set the renderjobs setting to a number of CPU's you can spare.

Per default it will set the setting to the number of cores you have, but it will also run on just 1 job and take a bit longer...

Example config from mapserver.json:

{
 "renderingjobs": 2
}

Database

The recommended database is Postgres if you have a busy server. SQLite will work too if the disk-access is good.

Personal experience: Don't worry about it if you have fast SSD's ;)

Network

I don't recommend serving the map behind a slow residential internet connection. An upload-bandwidth from 10 MBPS upwards will do the job pretty ok though:

Recap

If your setup looks something like this, don't worry about performance:

  • 4+ cores
  • 8+ GB RAM
  • 20+ GB SSD
  • Postgres DB
