--- Comment #2 from steve szmidt <st...@szmidt.org> --- FreeBSD does have Posix SHM. Looking at how it has been working just great for a long time and only recently started slowing down so even if it's done differently how come it worked flawlessly for years? I don't know how kactivitymanagerd is supposed to work/use the three files on a daily basis. For example, is it taking content from database and moving/copying it? I see that database is usually a couple of days behind database-shm and database-wal. The latter two are usually within the same day. database varies in size typically a few hundred K to a few M. database-shm is always 32768. Content is usually mostly zeros. On the set of files that really slowed down Plasma -shm had 77 bits. On my current with much less visible slows we have 1f8 bits (at the beginning of the file). database-wal varies but have about 2.7Mb of data. As you can tell I'm fumbling in the dark as I don't know how to really trace down what is going on or what to look for. Though what seems obvious is that -wal is a sqlite db, the -shm is a copy of what should be in SHM and database is a clear text where the content is copied not moved from. When I use a LOT of nodes in Inkscape, that is where I typically notice a slow. Recently I had a pretty simple image and I would sit around waiting for quite a while after making a change. Then I noticed that if I went to a different window and clicked it seem to snap out of it and catch up with updating the screen. As a side note, I've not seen any odd behavior otherwise. I've used KDE since the early days and never found anything that I liked better so I'm quite familiar with it. An annoyance is that it does not remember that I'm using virtual channel 4 on the sound card and have to tell it each time I boot. I'm not a C developer so I can't trace it myself. -- You are receiving this mail because: You are watching all bug changes.
