Apache OpenOffice (AOO) Bugzilla – Issue 67414
OpenOffice applications use only one processor

Hi, sorry, if this is the wrong project / subcomponent; it's only a guess. My observation with OpenOffice calc application is that it does not use dual core processors and I would assume, it will not use multi processors either. I have a dual core Athlon X2 4200+, but when running OpenOffice calc, the CPU load never gets beyond 50% (Of course both cores are involved, this is due to the OS and the scheduling policy, but both together sum up to 50% or below). I would assume, this is also true for other applications, so I put this issue to the framework project. It would be nice to use the full computing power at your hand, especially for long running operations in calc like recalculating a huge spreadsheet. I know changing the application to multi threaded is not easy and requires new algorithms if applied to an operation like calculation. But as dual cores / quad cores become more and more standard, it will be necessary. At least this would allow to run more then one document in parallel, when one is doing recalculation, the other window still will be usable and reacting. Which is not the case in the moment. Loading a spreadsheet will block all other spreadsheet windows open already.
