Benchmarks

Do you have some performance numbers? Please add them here!

Don't forget to state:

• CPU, RAM, HDD (SSD?)
• Imposm version
• OSM file (size, date and region, if it is an extract)
• used mapping (create a gist)
• complete command line
• important lines from the output (or complete output as a gist)
• du -h /tmp/imposm3_cache
