--- Comment #34 from David Faure <fa...@kde.org> --- Keep in mind that if most of the time is spent waiting (for I/O, network, mutex....) then using hotspot to look at CPU cycles will tell you nothing. You want to check the "off-CPU profiling" checkbox in hotspot, and look at wait times (in the flamegraph, look at the combobox which says "cycles", change it to "off-CPU Time"). If you get errors about sched_wait or something, run this script: http://www.davidfaure.fr/kde/perf-init -- You are receiving this mail because: You are watching all bug changes.
