Having many elements in inspector, editor becomes extremely slow and an error is thrown
Steps to reproduce:
1. Download and open the attached project
2. Attach the ArcenAIMovementTypeData.cs script to a gameobject
3. Enter 70 or more in to the element count in any of the fields
4. Keep expanding them and observe preformance
Expected result: little to no performance impact
Actual result:
"Optimized GUI Block text buffer too large"
- 30+ editor starts slowing down
- 70+ editor becomes extremely unresponsive
- 150+ editor freezes entirely(set amount in 5.6, then imported back into 2017)
Reproduced on 2017.1.0a1, 2017.1.1p4, 2017.2.0f1, 2017.3.0b3
Not reproduced on 5.6.3p4*
Regression introduced in 2017.1.0a1
Notes: *5.6 appears to handle this much better, only having a significant performance impact impact past 150 parent elements

I'm currently experiencing this problem in 2017.4.3f1. I know this is fixed in Unity 2018.1.
But will this be fixed in the LTS 2017 branch? I don't want to upgrade to 2018.1 because I want to stay on a stable version of Unity.

I've personally ran into this bug when using a custom [system.seralizable] class I had around 1000+ of these in a list, I don't know why you need to see them in inspector but my work around was simply something like this
if you have a list<GameObject> objects and its length is 1000 but you want to get the 25th object, create a public GameObject object and assign that to objects[25] then you can view that single one in the inspector.

We have a list of around 1000 entries. Since the 2017 versions we are unable to view the list past 500 entries in the inspector . The editor starts to lag and sometimes even crashes. Items past the 500 mark aren't shown and we are unable to add extra entries.

I have a long list - 5000+ entries. I can understand it's not reasonable to show all those entries in the editor, but the slow down (in unity 2017.2) means I can no longer inspect the offending asset. I can't even twirl the list closed as when it's selected as unity grinds to halt.
