Why Does Plex Get Slower With Extra Resources

What constitutes too many resources though?
More than the system has a use for.

I have 24 threads available. I allocated 4 of them to this task and 32 GB of memory, which is exactly 50% of the memory. There are no other VM's running in the hypervisor currently (online or offline).
Does the system ever use all of those resources?

Rarely, but it does. I've shared my media server with a lot of family etc, so it CAN hit that ceiling but everyone has to be using it at the same time and we're all different time zones.

So you have to decide between tuning for slow times or peak ones

So, if these resources were in use constantly I would not slow down but because they aren't it becomes a resource management problem? What is the difference between in use resources vs. our of use resources to the kernal?

Depends on what you consider slowing down. Having an engine too big for normal driving takes a toll on highway efficiency. But if you NEED it from time to time, then you'd have less power than necessary when you need it. If you were using all your resources all the time, there is nothing to slow down from, it's just at capacity.

One is being used to service a need, the other is just in the way and has to be managed without adding any value.

So if I had a need to use these resources Plex would still be slow but there would be a good reason whereas now it would be slow for no reason. That's what you're saying?

Right. You must decide what you are going to tune for. Throwing resources at a computer doesn't just make it faster, it only makes it faster if there is a way to utilize those resources. When a workload runs at different rates, you have to decide what you are tuning for... max, average, 95th percentile, etc.

Think about a closet. If you have five shirts, you need a closet to put them in. But not a big closet. Making the closet bigger will not speed up finding your shirt in the morning. And if you then have to clean the closest and sometimes you lose your shirt in it because it is so big, it actually slows you down. An unnecessarily large closet actually hurts you instead of helps you. But if you sometimes need a thousand shirts stored in there, you might determine that having a big closet is worth the wasted space and energy to handle the occasions when loads of shirts arrive and need to be stored.
