unbound unequal distribution of load

Post by cburns » 2017/03/21 19:02:46

Hello,

Running CentOS Linux release 7.3.1611 (Core) using unbound-1.4.20-28.el7.x86_64 I am having issues with unbound not load balancing across threads correctly. This issue is not present when using 3rd party repo or other distributions. I would really like to use the standard supported package of unbound in production but without equal distribution of load across all threads I am stuck.

Relevant snippet of configuration

msg-cache-slabs: 64
rrset-cache-slabs: 64
infra-cache-slabs: 64
key-cache-slabs: 64
rrset-cache-size: 4096m
msg-cache-size: 2048m
so-rcvbuf: 8m
so-sndbuf: 8m
outgoing-range: 8192
num-queries-per-thread: 4096

Also it looks like the key unsupported command maybe

# so-reuseport: yes

Any advice?

Thanks,
