Hi, XWiki version 7.1.2. We use Tomcat and MySQL. In query statistic we see many long queries such as below: # *Query_time: 49.708503 * Lock_time: 0.000089 Rows_sent: 0 Rows_examined: 4979 SET timestamp=1477308512; select visitstats0_.XWV_ID as XWV1_22_, visitstats0_.XWV_NUMBER as XWV2_22_, visitstats0_.XWV_NAME as XWV3_22_, visitstats0_.XWV_CLASSNAME as XWV4_22_, visitstats0_.XWV_IP as XWV5_22_, visitstats0_.XWV_USER_AGENT as XWV6_22_, visitstats0_.XWV_COOKIE as XWV7_22_, visitstats0_.XWV_UNIQUE_ID as XWV8_22_, visitstats0_.XWV_PAGE_VIEWS as XWV9_22_, visitstats0_.XWV_PAGE_SAVES as XWV10_22_, visitstats0_.XWV_DOWNLOADS as XWV11_22_, visitstats0_.XWV_START_DAT E as XWV12_22_, visitstats0_.XWV_END_DATE as XWV13_22_ from xwikistatsvisit visitstats0_ where visitstats0_.XWV_UNIQUE_ID='10.10.10.10Mozilla/4.0 (com patible; MSIE 7.0; Windows NT 6.1; WOW64; Trident/7.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; .NET4.0C; .NET4.0E)' and visi tstats0_.XWV_END_DATE>'2016-10-24 13:57:42' order by visitstats0_.XWV_END_DATE desc; If I understand correctly these queries check if the user entered the last 30 minutes. But why ? And why so long query time ? I try to reproduce in mysql console (do select for my unique id for last 30 minutes) and query so fast (~0,1s) -- View this message in context: http://xwiki.475771.n2.nabble.com/Strange-and-too-long-sql-query-to-statist… Sent from the XWiki- Users mailing list archive at Nabble.com.
