| Resumo: |
The FreeBSD operating system supports many platforms. It also tries to use any specific behavior given by the platform that might improve its performance. With the introduction of processors with multi-core capabilities many opportunities to optimize various operating system’s tasks became known. Operating systems like Debian/Linux have started taking advantage of the multi-core in many ways. One of those was the system initialization sub-system. Systemd, used on Debian/Linux, paralleled the service initialization, therefore decreasing the time taken for it to be done. FreeBSD is one of the systems that didn’t change, keeping a sequential service initialization. The objective of this work is to propose changes to the FreeBSD service initialization scheme making it parallel and evaluate those changes in comparison to the currently used system. The results show a decrease in initialization time when the proposed solution is combined with a quad-core processor. It also shows that the diference between FreeBSD and others systems goes beyond parallelism. |
