Tyler, thanks a lot for taking the time to examine the issue and writing such a complete response. I agree with all your points.
I'll take this as an opportunity to try to learn more about profiling and user/kernel space switching and optimization, because this made me curious: > Since the recommendation includes flushing the buffers before exiting from the kernel to userspace, > workloads which are syscall heavy are likely to see the largest performance hit. My emulator is basically a simple asm parser with SDL2 as graphic backend and I'm not doing (that I'm aware of..) any ioctl or syscall. So I need to understand what is happening and what I'm doing work. Back to study now :-) and thanks again -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1829255 Title: Sever performance degradation after updating to 5.0.0-15 due to mds mitigation To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1829255/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
