Apache Open Office fast." href="show_bug.cgi?id=113158">Bug 113158</a> File attached: A sample document showing slow response: scrolling, selecting cells and dragging across spreadsheet, and traversing with left/right arrows across spreadsheet. Sporadic performance from moderately affected to badly impaired. Apache Open Office is lightning fast and appears not afflicted. It's possibly a memory/CPU resource issue - it's worse when an anti-virus scan is running. LibreOffice can be slow and unresponsive in comparison to Apache Open Office. I have a feeling it depends on the background processes that are running. LibreOffice may be very hungry. I am wondering if Apache OpenOffice does the cell selecting and any formula recalculating sequentially as serial tasks and LibreOffice does them combined. The Dell 755 (Windows 10 Pro 64-bit) doesn't prompt that there is a low virtual memory and Process Lasso (A CPU optimizer that improves mouse responsiveness ) or Task Manager doesn't show a huge CPU or RAM problem. Apache Open Office runs rings around LibreOffice in this task. There is criticism appearing on the Internet. The sample spreadsheet is small; if a "Find and Replace" dialogue box is placed on the spreadsheet it increases the unresponsiveness of LibreOffice as the bordered cell is traversed across and below it. Apache OpenOffice developers designed a super product and Java frustrated it. I use an old version for the letter wizards. It's tough on LibreOffice. Puzzling!</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
