Server config Info:
Couchbase server version: 6.0.1 Community Edition (build-2037)
Couchbase Java SDK version: 2.7.4
I have setup a Couchabse cluster consist of 4 nodes.
Cluster 1 - (Server 1,2,3,4):
Total Processor: Output from nproc is 8 with 1 core each.
Total RAM: ~100 GB
No of Buckets: 2
RAM/Quota Usage: 27.5 GB
I am running a performance test on couchbase server with 10 users with the throughput of 4k Txns/sec. Exactly after 2.30 hours i see a drop in throughput which leads to only 2700 Txns/sec. This happens everytime i rerun the test.
In the same case, when I run the test with older version of Couchbase (4.x). I didn’t experience this type of issue and also the throughput is very consistent (~3500 txn/sec) all over the run.
Does anybody has idea on how to troubleshoot the root cause of the degradation after 2.30 hours.? It would be great if someone shed some lights on where to look at ?
