Summary: Memory Management Freebsd Guest On QEMU-KVM HOst
Product: Base System
Version: 11.0-RELEASE

OS: Any
Status: New

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
