System Information
Operating system: Windows-10-10.0.17134 64 Bits
Graphics card: GeForce GTX 1050 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 430.64

Blender Version
Broken: version: 2.80 (sub 74), branch: master, commit date: 2019-07-03 09:54, hash: f990c23bcf
Worked: (optional)

Short description of error
Scenes with a thousand triangles object and subsurface modifier level two cause the "last operator: add mesh", begins to have delay, more complex scenes generate more delay, is it normal?

**note: If I use the transformation tools in the object properties panel there is no lag

Blender 2.79 with six objects of the same characteristics generates a similar delay.

example_280.blend

Exact steps for others to reproduce the error
[Please describe the exact steps needed to reproduce the issue]
[Based on the default startup or an attached .blend file (as simple as possible)]

Not exactly sure I follow correctly:

what exactly is "last operator: add mesh"
are you adding stuff in objectmode (or with your object selected in editmode)?

With the default cube selected

Enter on edit mode
go to Edge menu in 3D viewport header and clic over Subdivide tool
press F9 to show Adjust Last Operation options and type 10 in Number of Cuts
switch to Object mode
add a Subdivision Surface Modifier
in properites of modifier type 4 in Subdivisions: Viewport
go to Add menu in 3D viewport header and add some mesh, a monkey for example
press F9 to show Adjust Last Operation options

**note: when the cursor is located in the middle of any number field, we can press left click mouse button, while pressing it, we can drag the mouse and the value is change

with the aforementioned method we try to change any location or rotation value and you will see that the object takes time to update
now press N to show the Transform options of the object
with the same method try to change any location or rotation value, you will see that the object is updated instantly

Think that’s expected currently, as using 'redo' panel effectively performs an undo/redo, which implies a full update of the scene (including that super-heavy mesh subsurf to be recomputed)…
