This educational repository shows how effective threads are when searching for words in long texts.
Warning
This program is made using pthread for syscalls, so It works only on POSIX systems (Linux, MacOS, ...)
We can immediately prove that multi-threading allows us to obtain significanly better performances for example using the tool on a file and search for a word with many occurrences such as Lorem in this case.
-
Starting the software with only one thread running will take about 1 second on my machine.
-
Instead, by launching the software using 12 threads we see a clear increase in performance, in fact the time has halved from 1094ms to 598ms.
