Hi, We are running 3 node solr cloud(4.4) in our production infrastructure, We recently moved our SOLR server host softlayer to digital ocean server with same configuration as production.
Now we are facing some slowness in the searcher when we index document, when we stop indexing then searches is fine, while adding document then it become slow. one of solr server we are indexing other 2 for searching the request. I am just wondering what was the reason searches become slow while indexing even we are using same configuration as we had in prod? at the time we are pushing 500 document at a time, this processing is continuously running(adding & deleting) these are the indexing logs 65497339 [http-apr-8980-exec-45] INFO org.apache.solr.update.processor.LogUpdateProcessor – [rn0] webapp=/solr path=/update params={distrib.from=http://solrhost:8980/solr/rn0/&update.distrib=FROMLEADER&wt=javabin&version=2&update.chain=dedupe} {add=[E4751FCCE977BAC7 (1612655281518411776), 8E712AD1BE76AB63 (1612655281527848960), 789AA5D0FB149A37 (1612655281538334720), B4F3AA526506F6B7 (1612655281553014784), A9F29F556F6CD1C8 (1612655281566646272), 8D15813305BF7417 (1612655281584472064), DD13CFA12973E85B (1612655281596006400), 3C93BDBA5DFDE3B3 (1612655281613832192), 96981A0785BFC9BF (1612655281625366528), D1E52788A466E484 (1612655281636900864)]} 0 9 65497459 [http-apr-8980-exec-22] INFO org.apache.solr.update.processor.LogUpdateProcessor – [rn0] webapp=/solr path=/update params={distrib.from=http://solrhost:8980/solr/rn0/&update.distrib=FROMLEADER&wt=javabin&version=2&update.chain=dedupe} {add=[D8AA2E196967D241 (1612655281649483776), E73420772E3235B7 (1612655281666260992), DFDCF1F8325A3EF6 (1612655281680941056), 1B10EF90E7C3695F (1612655281689329664), 51CBD7F59644A718 (1612655281699815424), 1D31EF403AF13E04 (1612655281714495488), 68E1DC3A614B7269 (1612655281723932672), F9BF6A3CF89D74FB (1612655281737564160), 419E017E1F360EB6 (1612655281749098496), 50EF977E5E873065 (1612655281759584256)]} 0 9 65497572 [http-apr-8980-exec-40] INFO org.apache.solr.update.processor.LogUpdateProcessor – [rn0] webapp=/solr path=/update params={distrib.from=http://solrhost:8980/solr/rn0/&update.distrib=FROMLEADER&wt=javabin&version=2&update.chain=dedupe} {add=[B63AD0671A5E57B9 (1612655281772167168), 00B8A4CCFABFA1AC (1612655281784750080), 9C89A1516C9166E6 (1612655281798381568), 9322E17ECEAADE66 (1612655281803624448), C6DDB4BF8E94DE6B (1612655281814110208), DAA49178A5E74285 (1612655281830887424), 829C2AE38A3E78E4 (1612655281845567488), 4C7B19756D8E4208 (1612655281859198976), BE0F7354DC30164C (1612655281869684736), 59C4A764BB50B13B (1612655281880170496)]} 0 9 65497724 [http-apr-8980-exec-31] INFO org.apache.solr.update.processor.LogUpdateProcessor – [rn0] webapp=/solr path=/update params={distrib.from=http://solrhost:8980/solr/rn0/&update.distrib=FROMLEADER&wt=javabin&version=2&update.chain=dedupe} {add=[1F694F99367D7CE1 (1612655281895899136), 2AEAAF67A6893ABE (1612655281911627776), 81E72DC36C7A9EBC (1612655281926307840), AA71BD9B23548E6D (1612655281939939328), 359E8C4C6EC72AFA (1612655281954619392), 7FEB6C65A3E23311 (1612655281972445184), 9B5ED0BE7AFDD1D0 (1612655281991319552), 99FE8958F6ED8B91 (1612655282009145344), 2BDC61DC4038E19F (1612655282023825408), 5131AEC4B87FBFE9 (1612655282037456896)]} 0 10 -- Sent from: http://lucene.472066.n3.nabble.com/Solr-User-f472068.html
