    41 containers:

    Are you noticing any stalling or stuttering when running apps or using multiple apps? If ‘no’ then I’d agree with the ones that are telling you it’s fine. Dats how Linux do. I’ve always been told to let Linux handle that unless it’s causing problems for you. And even then, after exhausting all other things that may cause this. Now whether that is sage advice, I couldn’t comment to that, however and anecdotally, it’s served me well.
