Performance

The hardware used for generating the data in these benchmarks was

windows 10 - 2.3 GHz Intel Core i5 and 8GB memory. 

All tests are performed on WSL(Ubuntu 18.04.2). And no color scheme used in windterm. Color scheme will result in approximately 2% loss and more memory usage.

• 97.6MB random text (102,401,504 bytes, 1,329,878 lines, generated and tested by random_test.sh)

In all cases, three runs were made to warm system caches. The reported numbers are the median of five runs.
