Telesto <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- Ever confirmed|1 |0 Status|NEEDINFO |UNCONFIRMED --- Comment #6 from Telesto <[email protected]> --- Lets start with: I have no clue how Calc code functions. So I only find slow and sluggish ;-) Well deleting a sheet takes 13 seconds which kind of matches comment 0 (never seen results of comment 2) 1. Open attachment 150858 [details] with or without Jumbo sheets on 2. Insert 10 new sheets 3. Copy Column A-C of sheet 1 4. Select sheet 2 t/m 10 (shift click) 5. CTRL+V (so pasting it into all 10) -> memory load to 2500 MB (even with 0 undo steps) 6. Delete one sheet of those sheets does take -> 13 seconds 7. Save -> takes more than 120 seconds 8. Close the document ... takes 10 seconds? --- I kind of expect instant deletion.. as there is no interdependence between those sheets (but well I'm not an expert to judge) CPU time appears to be actions by pumping lots of data around: ScTokenArray::Clone -> RtlAllocateHeap formula::FormulaTokenArray::Clear -> RtlFreeHeap -> RtlFreeUnicodeString might be Windows only? --- Offtopic With jumbo sheets LibreOffice being able to import lots of data (columns rows), but the bottleneck is the handling of the data some sensible way Has someone already tried to import some big dummy CVS with plain numbers which is making use of the jumbo sheet dimensions to simple see how well it goes. In the past it seemed the CVS loaded into memory first and next being copied to the sheet, consuming massive amounts of ram. -- You are receiving this mail because: You are the assignee for the bug.
