It is not clear to me exactly what you have benchmarked and compared. Can you please provide some additional information about the configuration of the benchmark, the track used, the hardware and the node configuration for the two scenarios?

Track:-metricbeat
Cluster1(Baseline):-8 Datanodes running on virtual machines each (28GB JVM and 125 GB total memory)
Cluster2(Contender):-8 Datanodes running as four processses on one Baremetal each processes is running with pre-defined compute (28GB JVM and 125 GB total memory)

Both clusters have 1 master and search node of same config

What are you worried about specifically? Median index-append throughput? Throughput for higher percentiles is inherently more noisy so I would ignore it for now.

Have you tried running this test three times for each configuration? This would tell you how much variability there is for a given configuration. Maybe it's higher than the 7% median indexing throughput you're seeing here.

No was just seeing better performance of vm based independent cluster than processes running on Baremetal .Also median index-append throughput is reaching 20% lower than standalone cluster when it was ran multiple times

Hey, from above comment I understand that this ( Median index-append throughput) metric is not of prime significance for evaluating two cluster baseline performance . Do let me know what is the metrics i should compare and rely on for testing a VM based Cluster and Pid based Cluster.

7

No, median indexing throughput is actually a good metric to use. We'll just need even more detail to understand why the performance could be different.

  • Are you using the same hardware for both clusters? Is it actually the same machine or two different ones?
  • Is it on cloud? (AWS has a baremetal offering)
  • What virtual machine technology are you using? Is there any isolation between them?
  • Can you be clearer about the 20% difference? The comparison you posted shows a 6.8% difference.

Yes we are using same hardware for both cluster's.
Pid based Cluster:-We are using two baremetal's having each bm has four instances of elasticsearch running on them resources(18 Cores 28GB JVM and 125 GB total memory for each pid) we have defined.
Vm based cluster:-We are using two baremetal's having each bm has four vm running on it which are running elasticsearch service independently . For resources 18 Cores 28GB JVM and 125 GB total memory for each vm we have defined.

It is on-premise cloud we are using.
Vm technology is kvm which is isolated .
These are the only difference in two cluster's that are compared.
These are comparison results i got for 20%
