When using Comet, the overall run time is reduced from 615 seconds to 364 seconds, a 1.7x speedup, with query 1

running 9x faster than Spark.

When using Comet, the overall run time is reduced from 640 seconds to 331 seconds, very close to a 2x speedup.

Running the same queries with DataFusion standalone (without Spark) using the same number of cores results in a 3.6x

Comet is not yet achieving full DataFusion speeds in all cases, but with future work we aim to provide a 2x-4x speedup

for a broader set of queries.

Here is a breakdown showing relative performance of Spark and Comet for each TPC-H query.
