https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=216760 Bug ID: 216760 Summary: Memory Management Freebsd Guest On QEMU-KVM HOst Product: Base System Version: 11.0-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: bin Assignee: freebsd-bugs@FreeBSD.org Reporter: kvanbiesen@gmail.com CC: freebsd-amd64@FreeBSD.org CC: freebsd-amd64@FreeBSD.org Performance Is Insanely low on when you install freebsd on a QEMU-KVM command to test: sysbench --num-threads=1 --test=memory --memory-total-size=1G run FREEBSD 11 on QEMU-KVM Operations performed= 1048576 (61139.84 ops/sec) 1024.00 transferred (59.71 MB/sec) UBUNTU 11 on identical KVM: Operations performed= 1048576 (2718486.33 ops/sec) 1024.00 transferred (2654.77 MB/sec) FREEBSD on bare metal: Around 2700MB/s I tested this on several installations; BBother freebsd 10 and 11. On Different KVM's, all the same results. Freebsd speeds are more than 60 times slower. Another user has tested this on servers KVM as in this reddit topic: https://www.reddit.com/r/freebsd/comments/5rtf05/abysmal_memory_perfomance_witch_freebsd_under/ FReebsd as guest under vmware and virtualbox performs as normal (speeds way over 2000MB) Gonna file a bug report with QEMU as well -- You are receiving this mail because: You are the assignee for the bug.help
