Hey, I have been debugging the problem Laurent mentioned lately that opening a password encrypted library causes Libreoffice to need a lot of cpu time even after loading finished.
During my investigation I now found two some interesting points: - the bug does not happen if you don't have thunderbird installed (maybe it is also necessary to have a profile) - the problem is in connectivity/source/drivers/mozab/bootstrap/MNSInit.cxx:228-235 -- the loop is sleeping for 1 ms and therefore running a thousand times per second without doing any real work because there are no events Since this also affects Loading of encrypted documents do we really need to initialize mozilla there? It should work now also without mozilla or am I missing something( see nssinitializer.cxx:197 ). If it is still needed, can't we stop the Mozilla_UI_Thread after we opened the encrypted document/library? Another easy solution to improve the situation might be to increase the timeout in MNSInit.cxx:235 from 1 to 10 or even 100, but I think that is more a workaround than fixing the underlying problem. Do we have someone who knows this code well enough to fix that for 3-5-0 or should we "fix" it there with the above mentioned workaround? I think a solution would be really necessary since this loop needs around 40% of one core on my fast development computer and Laurent mentioned around 40% of his whole cpu time( so I suspect 80% of one core for him ) I hope for some good ideas ;) Regards, Markus _______________________________________________ LibreOffice mailing list LibreOffice@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/libreoffice
