It could however be a Linux-only problem. Could you please try this on Linux? I am still having the same problem with 6.3 on Ubuntu 19.04 x86_64. On a fairly recent machine (Lenovo T460s), "New Spreadsheet", "Select All", "Data->Sort" takes about a minute before the "Sort" dialog appears. The waiting time is roughly quadratic to the number of columns selected: Columns | Delay --------+------ 200 | 3s 400 | 10s 600 | 20s 800 | 40s 1024 | 60s ("1024" is what "Select all" gives; the delays are only estimates) Up to 200 columns, the delay is acceptable. But then the delays start becoming annoyingly long. It seem that there is quadratic behavior in one of the data structures involved in creating the "Sort Key 1/2/3" drop-down lists which hurts performance when many columns are involved.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
