So I've just installed the Skyrim Special Edition and customized it with about 100 mods using Nexus Mod Manager. But even though I can play a heavily modded regular Skyrim without problems, I'm now noticing some performance drops while outside. They don't happen inside though. I've watched the performance monitor closely while playing; my memory is at about 40%, CPU at 20% utilization. Also, I don't have permanent low fps, it's more like microstutters every few seconds or so. This leads me to believe that I'm hitting some kind of bottleneck (possibly the hard drive – the game is installed on my HDD, not enough space on the SSD) when some of the HD textures from my mods get loaded or something similar.
I really don't want to turn off all my mods one by one to see which is causing the performance drops. So I would like to know if there is an easier way to find the culprit. Maybe a more advanced monitor that notices spikes in the system load or performance drops? Or an automatic analyser (like the automated mod organizing tools) that tells me which of my installed mods is likely to cause this sort of stuttering?
Any help is appreciated, I'm open to both automated and manual approaches, as long as they are not as immensely time-consuming as checking every mod one by one.

I would try a binary search:
You said that you have around 100 mods enabled so, try disable the last 50 mods.
Performance drop persists? Disable another 25 mods
Performance drop still persists? Disable another 12-13 mods and so on...
You could do it even if the Performance drop goes away with the first 50, just narrow down your search by dividing the active mods by half every time. It may take 2-3 hours but it's really worth the next 300 (guess, that could be even more) hours of gameplay.
Note: The performance drop may be caused by the mod load, so that there's no real culprit but all mods contribute to slowing your pc.
