Hi, So I did two test on two servers;
First server : with just replication every 20mn like you can notice: http://www.nabble.com/file/p22930179/cpu_without_request.png cpu_without_request.png http://www.nabble.com/file/p22930179/cpu2_without_request.jpg cpu2_without_request.jpg Second server : with one first replication and a second one during query test: between 15:32pm and 15h41 during replication (checked on .../admin/replication/index.jsp) my respond time query at the end was around 5000msec after the replication I guess during commitment I couldn't get answer of my query for a long time, I refreshed my page few minutes after. http://www.nabble.com/file/p22930179/cpu_with_request.png cpu_with_request.png http://www.nabble.com/file/p22930179/cpu2_with_request.jpg cpu2_with_request.jpg Now without replication I kept going query on the second server, and I can't get better than 1000msec repond time and 11request/second. http://www.nabble.com/file/p22930179/cpu_.jpg cpu_.jpg This is my request : select?fl=id&fq=status_published:1+AND+status_moderated:0+AND+status_personal:0+AND+status_private:0+AND+status_deleted:0+AND+status_error:0+AND+status_ready_web:1&json.nl=map&wt=json&start=0&version=1.2&bq=status_official:1^1.5+OR+status_creative:1^1+OR+language:en^0.5&bf=recip(rord(created),1,10,10)^3+pow(stat_views,0.1)^15+pow(stat_comments,0.1)^15&rows=100&qt=dismax&qf=title_en^0.8+title^0.2+description_en^0.3+description^0.2+tags^1+owner_login^0.5 Do you have advice ?
