Adrien Grand commented on SOLR-8251:
------------------------------------
I just saw the edit: don't worry Uwe, I didn't feel accused. On the contrary
I'm happy to be pinged about follow-ups of these things I've been working on
and to discuss them.
Regarding the produced scores, the reason it works this way is that it made
more sense to me to return 0 as a score when there are no scoring clauses
(hence no sources of scores).

> Key: SOLR-8251
> URL: https://issues.apache.org/jira/browse/SOLR-8251
> Project: Solr
> Issue Type: Bug
> Components: search
> Affects Versions: 5.3
> Reporter: wei shen
>
> I am trying to upgrade our production solr instance from 4.7 to 5.3.1.
> Unfortunately when I do load testing I find the MatchAllDocsQuery is much
> slower in solr 5.3.1 compare to 4.7. (solr 5.3.1 is faster in load test with
> queries other than MatchAllDocsQuery). I asked solr-user and discussed with
> Yonik Seeley. He confirmed that he can see the problem too comparing solr
> 5.3.1 and 4.10.
> here is the query I use:
> {code}
> q={!cache=false}*:*&fq=+categoryIdsPath:1001&fl=id&start=0&rows=2&debug=true
> {code}
> for me the query is consistently about 60-70% slower on solr5 than solr4.
> Yonik mentioned in his email "For me, 5.3.1
> is about 5x slower than 4.10 for this particular query."
