https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D254513 --- Comment #28 from Chris Collins <chrysalis@chrysalisnet.org> --- Ok I tested the following byte limits 1024 2048 4096 40960 0 (unlimited) In terms of reported cpu usage on proxmox graphs, 2048 and upwards are all = the same, also same with unlimited, so if proxmox even went a bit higher people probably would not have noticed. The peak usage reported inside the FreeBSD guest is higher on 2048 and vs 4= 096, and likewise 4096 vs 40960 and unlimited. But they seem to average out the same. I will report this to proxmox. Also even with unlimited, The idle system cpu usage is still about 3x vs without virtio rng (0.3% vs 0.1%), so seems to be less efficient but does d= rop to a level where most people wont notice it. --=20 You are receiving this mail because: You are the assignee for the bug.
