--- Comment #7 from [email protected] <[email protected]> --- I downloaded two public-domain books from Project Guthenberg: Leo Tolstoy's ~570,000-word War and Peace and Alain-Fournier's ~70,000-word Le Grand Meaulnes. Using Calibre, I converted the EPUB-format versions to DOCX, and using LibreOffice I saved them as ODT and TXT versions. I maintained LibreOffice 4.4.5.2 x86 as my primary (registered) LibreOffice installation and added 5.0.0.5 x86 and 5.0.0.5 x64 as parallel (unregistered) installs. I pointed the bootstrap.ini files of the parallel installs to my existing user profile folder, since LO5 uses the LO4 profile and since I had previously excluded my profile as a potential culprit in this bug. I then separately loaded each of the two books in each of the two formats in each of the three LibreOffice versions, waited for post-document-loading tasks (repagination and statistics updating?) to complete, and examined soffice.bin's background CPU usage in Task Manager. (System Explorer yielded similar CPU usage readings.) In 4.4.5.2 x86, soffice.bin *32's background CPU usage was: * A constant 0% for the 70,000-word TXT version of Le Grand Mealnes * A constant 0% for the 70,000-word ODT version of Le Grand Mealnes * Variable, between 0% and 28%, most often in the low to mid 20s, for the 570,000-word TXT version of War and Peace * A constant 0% for the 570,000-word ODT version of War and Peace In 5.0.0.5 x86, soffice.bin *32's background CPU usage was: * A constant 0% for the 70,000-word TXT version of Le Grand Mealnes * A constant 0% for the 70,000-word ODT version of Le Grand Mealnes * 48%-50% for the 570,000-word TXT version of War and Peace * 48%-50% for the 570,000-word ODT version of War and Peace In 5.0.0.5 x64, soffice.bin's background CPU usage was: * A constant 0% for the 70,000-word TXT version of Le Grand Mealnes * A constant 0% for the 70,000-word ODT version of Le Grand Mealnes * 48%-50% for the 570,000-word TXT version of War and Peace * 48%-50% for the 570,000-word ODT version of War and Peace I believe this "high-word-count" bug can be confirmed as new to, or aggravated in, both x86 and x64 Windows editions of 5.0.0.5. I cannot venture any guess as to why background CPU usage would be moderately high in 4.4.5.2 x86 for the plain-text version of the 570,000-word document but not for the ODT version. I'm uploading the two public-domain documents I used to carry out this test, in each of the two formats I tested (TXT and ODT). -- You are receiving this mail because: You are the assignee for the bug.
