    Description

      Looks like in build 1070 there is a regression in some of the views queries

      http://showfast.sc.couchbase.com/#/timeline/Linux/views/by_type/all

      80th percentile query latency (ms), 1 node, 20M docs, 3 views, 100 updates/sec, 100 queries/sec, stale=false, basic queries, default collection

      1069 - http://perf.jenkins.couchbase.com/job/leto/21592/console - 220

      1070 - http://perf.jenkins.couchbase.com/job/leto/21588/console - 248

      http://changelog.build.couchbase.com/?product=couchbase-server&fromVersion=7.1.0&fromBuild=1069&toVersion=7.1.0&toBuild=1070&f_couchbase-cli=off&f_eventing=off&f_kv_engine=on&f_magma=off&f_product-metadata=off&f_tlm=on

      Looks like there is 3 kv engine commits related to memory allocation. From the graphs it appears as though there is more free memory in the 1070 run: http://cbmonitor.sc.couchbase.com/reports/html/?snapshot=leto_710-1069_access_0477&snapshot=leto_710-1070_access_963d#6799c0925e8393e50adc1e168ec87cbd

            The toy build fixed the issue, but it doesnt seem like the fix has gone into official build yet

            The fix (V8) for MB-47980 also fixes this view regression.  Tested with build 7.1.0-2223.

            Build couchbase-server-7.1.0-2182 contains tlm commit f4c48aa with commit message:
            MB-47908: Revert to earlier v8 build on x86_64 platforms

            Closing this ticket.
