query timeout

[VladimirAlexiev]

The query "list" given at http://wikicite.org/statistics.html column "types" times out.

# List of publication types. See also https://www.npmjs.com/package/wikidata-taxonomy
SELECT ?item ?itemLabel ?itemDescription ?instances ?sites WITH {
  SELECT DISTINCT ?item { ?item wdt:P279* wd:Q732577 }
} AS %types WHERE {
  INCLUDE %types .
  { 
    SELECT ?item (COUNT(DISTINCT ?instance) AS ?instances) {
      INCLUDE %types .
      OPTIONAL { ?instance wdt:P31 ?item }
    } GROUP BY ?item
  }
   {
     SELECT ?item (COUNT(DISTINCT ?site) AS ?sites) {
       INCLUDE %types.
       OPTIONAL { ?site schema:about ?item }
     } GROUP BY ?item
   }  
  SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en". }
}

WD has a strict timeout of 1 minute. I guess you need to simplify it. Eg try removing the DISTINCT ?instance or cut out the ?site part.
