I've been doing some more investigation into some reported KDE4 slow downs, and am now pretty sure that its all related to the internal messaging in KDE, maybe related to how it talks to dbus. Here's what I've found so far:
First, one of the major areas where you notice the "slowness" is when you click on the start button to launch kickoff, or when you click an icon on your folderview on the desktop. It seems like after you click or double-click something to launch, it takes anywhere from 1-3 seconds before the cursor changes, and the program actually starts launching. If you open up a konsole session and run "tail -f .xsession-errors" and then try to launch an application this way, you'll see what I mean. It takes a few seconds before kdeinit4 gets the notification that we have double-clicked to start an application. At first I thought this was a problem with dbus, but I've done some more digging and found that launching the exact same command / app from qdbus is instantaneous: # qdbus org.kde.klauncher /KLauncher org.kde.KLauncher.kdeinit_exec "dolphin" "" "" "" If I run the above command, my bouncy cursor loads within milliseconds and dolphin loads immediately, no delay at all. So if my thinking is correct here, then somewhere between the time when I click or double-click, and a signal is generated, there is a 1-3 second delay before the request makes it to dbus, and the action is taken. This applies pretty much universally throughout KDE4 it appears, often programs run really fast, but when they start doing external messaging, thats were the slowdown occurs. So the question is, how do we fix it? Where should I be looking code-wise to find where all KDE messages pass through? Also, I haven't run KDE4 on Linux, is this problem there as well, or just specific to FreeBSD? Should I refer this to some other KDE bug / developer list to help examine this bug? -- Kris Moore PC-BSD Software http://www.pcbsd.com _______________________________________________ kde-freebsd mailing list kde-freebsd@kde.org https://mail.kde.org/mailman/listinfo/kde-freebsd See also http://freebsd.kde.org/ for latest information
