Bug ID: 146037
Summary: Autofilter is slow when filter conditions are set in
multiple columns
Product: LibreOffice
Version: 7.4.0.0 alpha0+ Master
Hardware: All
OS: Linux (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Calc
Assignee: libreoffice-bugs@lists.freedesktop.org
Reporter: suokunl...@126.com
Steps to Reproduce:
1. Open attachment 176404 (i.e., comment 2 in tdf#136838)
2. Click on the autofilter dropdown in column O (i.e. LC_Value), deselect the
first item (i.e. -1,255,773.47), OK.
--> Fast.
3. Then click on the autofilter in column S (i.e. MaterialNumber), and deselect
the first item (i.e. "(Blank)"), OK.
--> There is a 3s lag when clicking on the the autofilter dropdown. However it
is still good that the filter process itself is fast.
4. Then click on the autofilter in column H (i.e. Value), and deselect the
first item (i.e. "1.00"), OK.
--> There is a 3s lag when clicking on the the dropdown. Importantly, it takes
a long time (around 1min) with 100% (single-core) CPU for the filter process to
finish.
