In lorenzwalthert/gitsum: Parse and summarize git repositories

This report gives an overview of the performance on the refactor repo at commit 86acd4d319a755e0a05593f400ba636363630eba.

library("tidyverse")
read_rds("../benchmarking/at_86acd")

Before any optimization, the mean was about 0.8 for read and 0.9 for read and write. Changing the approach and use dplyr instead of nested lapplyr and some other modifications slightly slows down the performance. However, there is now a progress bar.

read_rds("../benchmarking/at_86acd")

Also, it was possible to use stringr for matching

read_rds("../benchmarking/at_86acd_dplyr_parse_one2.rds")

Further more, multipel strings were matched with one regex call

read_rds("../benchmarking/at_86acd_dplyr_parse_one2_extract_multiple.rds")
