Bug ID: 155260
Summary: Lots of CPU time spend in SwFieldType::GetXObject
while spell-checking
Product: LibreOffice
Version: 7.6.0.0 alpha1+ Master
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Writer

Reporter: [email protected]
Description:
Lots of CPU time spend in SwFieldType::GetXObject while spell-checking
Steps to Reproduce:
1. Have a Swedish dictionary installed and automatic spell checking disabled
2. Open attachment 155192. 90 seconds until on screen (OK)
3. Wait until CPU drops to 0%
4. Enable spell automatic spell checking.. I waited 300 seconds, but it didn't
finish. Memory usage keeps incrementing in small steps too
SwFieldType::GetXObject swlo
linguistic_DicList_get_implementation mergedlo
linguistic_DicList_get_implementation mergedlo
osl_getTempDirURL sal3
Nearly all the time is spend in SwFieldType::GetXObject
Actual Results:
Idle process keeps going..
Expected Results:
I'm lacking a decent benchmark. 4.4.7.2 has different idle timers. LibreOffice
5.2 is spending lots of time layouting tables
So random guess would be 180 seconds
Reproducible: Always
User Profile Reset: No

SwFieldType::GetXObject as such more in SwFrame::ImplFindTabFrame
