freeze is reproducible under Win8.1x64 using LibO 4.4.3.2 and 4.2.0.4 I see the same issue with AOO 4.1.0 so the bug is most likely inherited from OOo status NEW. I add Calc expert to CC list.

It is probably a performance issue. This copy (23000+ rows) finished in 13 minutes on a i7-4790. Version: 7.2.0.0.alpha0+ (x64) Build ID: 498c6b9f4ee53677381d10d41df0abc9782689c4 CPU threads: 8; OS: Windows 10.0 Build 18363; UI render: Skia/Raster; VCL: win Locale: hu-HU (hu_HU); UI: en-US Calc: CL
I think a bug 139444 is about the same problem

I have made some small improvements. But this is essentially a pathological test-case - every single one of those VLOOKUPs is going to return a different result, which means our query-result-cache is never hit, which means that such a copy-paste is just going to take a really really long time, and there is not much we can do about it.

Noel, thank you for your work here. So, will you plan to do anything else here? Or it require to full rework for that place?
