Abstract :
The high use of system calls in many applications has motivated research works focusing on reducing the overhead caused by these calls. In this work we implement three types of compound system calls, which are evaluated experimentally by taking into account their execution time in systems with 1 to 4 cores. All implemented system calls present performance gains when compared to their conventional counterparts. The data obtained through controlled experiments are analyzed performing ANOVA and Tukey tests. The best results show reductions in the execution time between 50 to 60 percent.
