  Now the same with zstd:
  
    $ time zstdcat -v -d wikidata-20190506-all.json.bz2 | cat > /dev/null 
    
    real    3m48.657s
    user    0m3.792s
    sys     0m58.768s
  
  here's the sizes:
  
    35G     wikidata-20190506-all.json.bz2
    39G     wikidata-20190506-all.json.zstd-def
  
  so zstd is about the same size compressed but is about 10 times faster 
decompressing.
