Subject: how to find a task through name faster?

hi all:
I found a way to find a task I need by name, test,  as below:
for_each_process(task) {
    if(strcmp(task->comm, "test")
        printk(“%s[%d]\n”, task->comm, task->pid);
}

But it is time-consuming to do so if I periodically want to know
whether "test" exist or not.
is there better way to do so?
