--- Comment #16 from David Edmundson <k...@davidedmundson.co.uk> --- Your log: 53.71% of the time spent handling X events from the DRI driver saying "I've done something". We're getting ~1 million of these events. How long did you have callgrind on for? It seems excessive. Because of that 30% of the total time is then spent in KDE code processing these X events. That's something I super optimised last month that you clearly don't have yet. Latest frameworks will bring a huge improvement for you as that's now down to near zero, making us ~30% faster. Though I don't get why we're getting so many of these events. Other thing that's potentially super important, that I hadn't seen before. 27% of the time is spend in __memmove in libc. Unfortuantely I can't really see what's going on there as we don't have symbols for libxcb (not sure if it's you who needs to install them or me) But one thing it could mean is we're swapping graphic card memory. Can you install intel-gpu-tools and run intel-gpu-top / intel-gpu-overlay and see if that says anything useful. -- You are receiving this mail because: You are watching all bug changes.
