            Bug ID: 109158
           Summary: slower loading of a huge AutoCorrect replacement table
           Product: LibreOffice
           Version: 6.0.0.0.alpha0+ Master
          Hardware: All
                OS: All
            Status: UNCONFIRMED

Description:
tested under Win7 x64 using LibO 6.0.0.0.alpha0+
Build ID: 4f17445c12dc26c4881c4e486215b58d26515f8d

loading a very big AutoCorrect replacement list such as the one I uploaded as 
attachment 134684

is slower in LibO 6.0.0.0 than in LibO 5.3.4.2

the same file takes 4 seconds to load in in 5.3.x and 10 seconds in LibO
6.0.0.0 alpha

this is a performance regression when dealing with huge autocorrect lists.
I also reported another issue regarding closing the replacement table Bug
109156.

basically LibO 6.0.0.0 is slower loading such lists and hangs while closing
them.

Steps to Reproduce:
click on menu "Tools/AutoCorrect/AutoCorrect Options" and count the time needed
to display the list.

Actual Results:  
LibO 6.0.x is 2.5 times slower that 5.3.x

Expected Results:
it should take the same time as in 5.3.x

Reproducible: Always
