> The script help doesn't specify which of the hashes is the reference and which is the baseline, which makes it hard to interpret the output of the run. I'm not sure but I think I may have been interpreting the order backwards. Can we clarify this in the help?

> $ ./bin/single_node_perf_run.py --help
> Usage: 
> single_node_perf_run.py [options] git_hash_A [git_hash_B]
> When one hash is given, measures the performance on the specified workloads.
> When two hashes are given, compares their performance. Output is in
> $IMPALA_HOME/perf_results/latest.
> WARNING: This script will run git checkout. You should not touch the tree
> while the script is running. You should start the script from a clean git
> tree.
> WARNING: When --load is used, this script calls load_data.py which can
> overwrite your TPC-H and TPC-DS data.
