Klustron VS Oracle TPC-H perf

Overview of Test Results

Using the TPC-H benchmarking tool, tests were conducted on Klustron v1.4.1 and Oracle v19.14.0.0.0 to obtain performance results.

With a data volume of 100G, Klustron took a total time of 307.9 seconds, while Oracle took 782.8 seconds, making Klustron's performance 2.5 times that of Oracle.
At a data volume of 200G, Klustron's total time was 1631.57 seconds, and Oracle's was 2599.11 seconds, with Klustron's performance being 1.5 times that of Oracle.
At a data volume of 500G, Klustron's total time was 10197.26 seconds (with an exception in query Q21), and Oracle's total time was 5827.13 seconds, making Oracle's performance 1.7 times that of Klustron.

Precautions

Before importing data into Oracle, ensure that enough tablespaces are created to prevent data import failure due to insufficient space.
The disks of the machines used for the test are not enterprise-level disks, which may inevitably affect some performance results.
