Bug ID: 150979
Summary: FILEOPEN: ods, opg, opd files open very slowly after
startup on Windows
Product: LibreOffice
Version: 7.0 all versions
Hardware: x86-64 (AMD64)
OS: Windows (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Calc
Assignee: libreoffice-bugs@lists.freedesktop.org
Reporter: c...@tompassin.net
Description:
A tiny file -spreadsheet, Impress, or Draw - takes 30 - 40 seconds to open the
first time after LO has been restarted. This is only on Windows; the same file
opened immediately on a Linux Mint VM. An .xlsx version of the same tiny file
opens immediately after startup. Even if the .xlsx version was opened first,
the .ods file still takes that 30 - 40 seconds to open. Once the .ods file has
been opened, then the .odg and .odp documents open immediately.
Writer files do not show this behavior.
I am reporting this for V7.4.1.2 but it goes back many versions.
Steps to Reproduce:
1.Open Calc, type "this is a test" into cell A1. (The actual behavior occurs
for any spreadsheet).
2.Save as open-test.ods, then as open-test.xslx.
3.Close LO.
4. Start Calc. Open open-test.xslx. Observe immediate opening.
5. Open open-test.ods. Observe very slow opening.
Actual Results:
The open-test.ods file takes 30 - 40 seconds (by counting, not a timer) to open
even though it has only a short string in only one cell.
Expected Results:
The test-open.ods file should have opened immediately.
Reproducible: Always
User Profile Reset: Yes
Additional Info:
Note that if you close test-open.ods and then re-open it, it loads immediately.
The slow opening occurs only the first time after restart. It is not
necessary to first open the test-open.xslx file to demonstrate the behavior,
but doing so narrows down the cause to something specific to LO files.
Create similarly tiny Draw and Impress files, and repeat the same steps, each
time closing and restarting LO. Note that I do not preload LO.
Turning Skia on and off did not cure the behavior. Without Skia, opening
test-open.ods seemed to take even longer.
There is no option to disable OpenGL in the Tools/View options.
