Running on top 10 commits on main tree with old and new script:
$ time ./devtools/checkpatches.sh -n10 10/10 valid patches real 0m32.570s user 0m30.517s sys 0m2.256s $ time ./devtools/dpdk-checkpatch.py -n10 10/10 valid patches real 0m0.255s user 0m0.214s sys 0m0.040s 32.5 seconds down to a quarter of a second is a massive gain. Looking forward to switching script for checking patches in future! /Bruce
