Hi, I'm currently testing Solr query execution performance (over http and SolrJ), and, using HTTP with JMeter, I see that the response time increases with the number of concurrent request (100 simultaneous request in my case).
To understand where Solr takes more time, I use the debug=timing parameter. And I see this kind of response : <?xml version="1.0" encoding="UTF-8"?> <response> <lst name="responseHeader"> <int name="status">0</int> <int name="QTime">3003</int> <lst name="params"> <str name="q">uuid:FA2C9342381E3969E04456C8B4C639A9</str> <str name="debug">timing</str> <str name="indent">true</str> <str name="wt">xml</str> </lst> </lst> <result name="response" numFound="1" start="0" maxScore="15.705477"> <doc> <bool name="bc_repe_pro">false</bool> <str name="type_personne">P</str> <str name="numero_dossier_client">30000224149</str> <str name="uuid">FA2C9342381E3969E04456C8B4C639A9</str> <str name="cle_recherche">FA2C9342381E3969E04456C8B4C639A9_P</str> <long name="_version_">1518391139884859416</long></doc> </result> <lst name="debug"> <lst name="timing"> <double name="time">0.0</double> <lst name="prepare"> <double name="time">0.0</double> <lst name="query"> <double name="time">0.0</double> </lst> <lst name="facet"> <double name="time">0.0</double> </lst> <lst name="mlt"> <double name="time">0.0</double> </lst> <lst name="highlight"> <double name="time">0.0</double> </lst> <lst name="stats"> <double name="time">0.0</double> </lst> <lst name="debug"> <double name="time">0.0</double> </lst> </lst> <lst name="process"> <double name="time">0.0</double> <lst name="query"> <double name="time">0.0</double> </lst> <lst name="facet"> <double name="time">0.0</double> </lst> <lst name="mlt"> <double name="time">0.0</double> </lst> <lst name="highlight"> <double name="time">0.0</double> </lst> <lst name="stats"> <double name="time">0.0</double> </lst> <lst name="debug"> <double name="time">0.0</double> </lst> </lst> </lst> </lst> </response> I see that the QTime is "3003", but I get nothing (0.0) for all other times. Do you know what does it means ?
