Listing 1 shows a simple example of a DTrace script that counts the number of system calls made by each process. (Note the use of the dictionary to associate counts with processes).

Reducing the code had many benefits, including performance (code size over the wire is where it really counts with script) but also in reducing the tangled dependencies we used to have.

For a company hiring, it does not replace a background screening firm but automates and centralize the screening process and counts with tools to prevent impersonation and fake reviews.
