LibreOffice 5.4 Adds More New Features, Improves Office File Format Compatibility (betanews.com)
The Document Foundation has released LibreOffice 5.4. Again, it's on time, arriving six months after the release of LibreOffice 5.3. From a report: LibreOffice 5.4 is "the last major release of the LibreOffice 5.x family," and like other point releases is a major one, adding features across all components and incrementally improving compatibility with Microsoft Office document formats. Highlights include a new standard color palette based on the RYB (Red Yellow Blue) color model. File format compatibility improvements include better support for EMF vector images and higher quality rendering of imported PDF files (with support for embedding video in exported PDFs from Writer and Impress). Also added is OpenPGP key support for signing ODF documents in Linux. LibreOffice Writer adds new context menu items for working with sections, footnotes, endnotes and styles. Users can now import AutoText entries from Microsoft Word .dotm templates. The full structure of bulleted and numbered lists is now preserved when pasted as plain text, and users gain the ability to create custom watermarks for their documents via the Format menu.
Since I can use it on a eeepc netbook I can't see where your speed complaints are coming from.
It kind of looks like you are making them up unless you are using it on hardware from last century.
Are you actually talking about Open Office or go-OO or the newer Libreofice? or are you trying to conflate a decade old issue to tarnish a modern product?
The original Sun OpenOffice download for a number of reasons (like Sun) was a slower than the patched go-OO version which was used by the major Linux distributions. It had a reputation for being glacial in comparison, and go-OO wasn't fast by any means, Apache have really hardly started fixing this yet.
Go-OO and early Libreofice still had a number of quite significant problems with file loading as well as graphics performance due to Sun's tendency to want to leave working code alone or patch minimally even when it worked poorly or got in the way. The early part of Liberofice 's history involved tearing a lot of cruft out, as such many of the most blatant issues where fixed quite early but many remain. For an example see https://people.gnome.org/~michael/blog/2012-01-09-unused.html , but much used and outdated code was also a problem.
Newer Libreofce is significantly faster, removal and replacement of a lot of old manual timer stuff for GUI events, for example (along with a lot of other work), has made things snappier to use. Performance profiling and upgrading of the input filters has progressed to the point that for my small documents loading is effectively instant and start-up is less than 1 second on my old machine. Despite this speed is still dependant on OS, and the specific document loaded. It is not unusual for the newer versions of Libreofice to be better than Microsoft Office in speed but it is also not unusual to be worse. In addition some windows graphics performance upgrades will have to wait on the deprecation of XP.
What kills Libreoffice is bloat and feeping creaturitis.
Nothing "kills" Libreoffice. It is a staple feature of any Linux installation, widely used on Windows, and a credible threat to Necrosoft's cozy monopoly.
When all you have is a hammer, every problem starts to look like a thumb.
