Compare resutls

Example:

./compare_results.sh \
    ~/regression_results/results_20250113_*.json \
    ~/regression_results/results_20250120_*.json

Extend the runtime of the tests

Option 1 - Double/Triple the data

This can be done by increasing FILESIZE and FILESIZE_MULTI attributes

Option 2 - Add more iterations

IOR Supports running multiple iterations to get more stable averages

srun -n 1 ior -w -r -i 3 -o ${TESTDIR}/ior_single -t $BLOCKSIZE -b $FILESIZE -F
#                   ^^^
#                   Run 3 times and average
