    That could be a complete waste of time. The idea that every performance problem can be solve by multithread is simply wrong.
     
    In many cases, the problem will stay the same and you just add extra overhead. For example, if your problem is caused by a single slow query, multithreading can't help you.
     
    In other cases, multithreading may can make things even worse. For example, you'll have several threads trying to work with the same records and they'll block each other by locks in database.
     
    Or you're simply unable to split the process to smaller pieces that can run in parallel.
     
    In my opinion, you should forget multithreading for now. What you really need is measuring what's actually slow. Only when you know the problem, you can design a solution addressing the it.

    Hi,
     
    I fully concur with Martin here. Note that depending on the use case, multithreading might be even slower. When you can share details about what batch jobs are slow, and if you are referring to standard periodic tasks or customizations, we might be able to assist. Note that you first need to know what exactly is causing the slowness. 
    Compare it in this way: If you replace one truck with 5 sport cars, it won't work in a traffic jam.
