    Description

      Observing lesser number of GET & SET operations while running transactions as compared to regular workloadA load test .

      Also high CPU utilization 

      Here is a comparison of two load tests with durability set to None .

       

      stats Transaction Test KV Load Test
      OPS ~11000 ops/sec (7748 trans per sec) ~328880 ops /sec
      cmd_get ~37000 ~164440
      cmd_set ~70000 ~164440
      Throughput  7748 trans/sec ~328880  ops/sec
      server side cpu utilization (%)  ~ 90 % ~90 %
      workload 1 Transaction = 4 READ + 3 UPDATE  1 OPS = 1 READ or 1 UPDATE
      workload Distribution  100% transactions 50:50 READ:UPDATE

       

      Cluster Config :  4 Nodes, 2 Replicas , 12 vCPU, 64 GB RAM

      Test Config : 10M Items , 1KB docSize

      Client Info : YCSB , 1.0.0-beta.1 3.0.0-alpha.6 , Uniform requestdistribution, 480 concurrent workers

      WORKLOADTA : Number of ops in Single Transaction 4 , 4 READS, 3 UPDATE, Durability 0
