Improve Structure / Cache efficiency Background: there is a new (experimental) valgrind tool called 'DHAT, a dynamic heap analysis tool'. It generates output a little like this. The data is rather hard to interpret, and has some false positives (eg. the opendir hits), but can point to large chunks of memory that are allocated written to, but then never read from, or identify holes in frequently used structures, and so on. It would be great to do further analysis on the data, discuss it on the list, and then patch the various classes / structures / calls in most need. Skills: building, C++ hacking, C++ ABI understanding, patience.
Deteted "Easyhack" from summary
adding LibreOffice developer list as CC to unresolved EasyHacks for better visibility. see e.g. http://nabble.documentfoundation.org/minutes-of-ESC-call-td4076214.html for details
Migrating Whiteboard tags to Keywords: (EasyHack DifficultyInteresting SkillCpp) [NinjaEdit]
JanI is default CC for Easy Hacks (Add Jan; remove LibreOffice Dev List from CC) [NinjaEdit]
Re-evaluating the EasyHack in 2023 It will be useful to do some analysis with DHAT/valgrind and then improve the code, but as the area and the scope of the task is not very clear, I remove the EasyHack tag.
