I put my quick result here: http://snippets.xwiki.org/ xwiki/bin/view/Extension/Performance%20of%20SOLRQL%20vs%20XWQL/ In short, it seems that XWQL wins by a factor of at least x2. Is that your experience too? Let me know if I’ve made a mistake somewhere. Thanks -Vincent

Doing a “LIKE” one is interesting. I’ll try to do one. On a small data set, the advantage is still for XWQL, see http://snippets.xwiki.org/xwiki/bin/view/Extension/Performance%20of%20SOLRQ… Note that the majority of queries done by XWiki during a page rendering are done on small result set. But indeed, it would be interesting to load XWiki with, say 2M pages and do the test again.

On larger volumes you’d need to use an external SOLR which would perform better but you’d suffer from the marshalling/unmarshalling of requests/responses. > > Thanks > -Vincent > >> >> Ludovic >> >> Le 4 mars 2018 11:46, "Vincent Massol" <vincent(a)massol.net> a écrit : >> >> Hi devs, >> >> I was curious to know how SOLRQL compared vs XWQL (for example to progress >> on the idea of moving more to using SOLRQL for doing queries and thus being >> able for ex to use a store based on, say, git). >> >> I put my quick result here: http://snippets.xwiki.org/ >> xwiki/bin/view/Extension/Performance%20of%20SOLRQL%20vs%20XWQL/ >> >> In short, it seems that XWQL wins by a factor of at least x2. >> >> Is that your experience too? >> >> Let me know if I’ve made a mistake somewhere. >> >> Thanks >> -Vincent >
