High CPU load by http.so 2
I have occasionally observed that behavior. From what I can tell for me it happened when a QML Image was downloading a remove image. This would use KIO AccessManagerFactory and translate QNetworkAccessManager calls to KIO and somewhere in there it ends up hogging CPU. Bug 392768 seems to be origin of this issue, too. *** This bug has been marked as a duplicate of bug 392768 *** |
Created attachment 115826 [details] High CPU load by http.so 1 Periodically, http.so processes started by Ktorrent begin to load CPU intensively. There are multiple such processes running, so the total effect is 20-40% CPU load, according to KSysGuard. This period of high CPU usage lasts for about 20-30 seconds, then the CPU load goes back to normal. These high CPU usage periods happen repeatedly at various intervals, I've seen anywhere from about a minute and around 5 minutes. I suspect, the intervals may have to do with how often Ktorrent contacts the torrent trackers. I've attached a couple screenshots showing high CPU usage.
