Best practice with timers

Hello guys!? I would like to ask a question about the use of timers.? Suppose I have several systems that do checks from time to time, the best way would be to create a single timer that does all the checks or create multiple timers to check each thing?? Which way would be the most optimized and least burdensome on the server?

Code 1:

SetTimer("ExecuteAll", 1000, false);

public ExecuteAll()
{
    // Verification 1
    // Verification 2
    // Verification 3
    ...
}



Code 2:



SetTimer("Execute1", 1000, false);
SetTimer("Execute2", 1000, false);
SetTimer("Execute3", 1000, false);

public Execute1()
{
    // Verification 1
}
public Execute2()
{
    // Verification 2
}
public Execute3()
{
    // Verification 3
}
