Also the SOLR API you used is checking the right for each result which
is not the case for the xwql one.

Well "XWQL" does not really mean much since that's not what is
executed. Better indicate the database you are comparing with SOLR, I
guess it's HSQLDB here. You would most probably don't get the same
result with a different database and it also depends a lot on the
database configuration (how much is cached, etc.).
Good point.
It’s still interesting to know that with our standalone distribution it would be faster
with XWQL on HSQLDB than SOLR queries.
Next step: test this on mysql.

Yes I agree. Obviously if we want to check this further we need to do more tests. 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.

I’m lacking the data to do volume testing both in term of quantity of data and in term of
load on XWiki.
Another point to consider: this test is done with SOLR being embedded (which should
provide the best perf on low volumes IMO). 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.
