Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
System Information
Operating system: OS X 10.14.5
Graphics card: Radeon Pro 460 & Radeon RX 580
CPU: 2,9 GHz Intel Core i7
Blender Version
Broken: 2.80
Worked in: 2.79b (silky mooth up to 500k vertices)
Short description of error
Zoom & Panning 3d viewport have 0.5sec start lag only after adding 15k vertexes in Solid and Look Dev shading. The FPS is decent while rotating, but starting zoom & rotate gestures has already 0.5sec lag. In Eevee starting rotation & zoom is actually faster so thought this might be considered as bug. Switching GPU doesn't help, probably CPU-bound.
Exact steps for others to reproduce the error
Open .blend with more than 15k vertexes on a recent MacBook Pro

Thanks for the report, we plan to look into performance improvements, but are not tracking them as individual bug reports.
