pkgng and freebsd-update slow on the host system

[src386]

Hi everyone,

I'm using FreeBSD 10 :

FreeBSD TARDIS 10.0-RELEASE-p7 FreeBSD 10.0-RELEASE-p7 #0: Tue Jul  8 06:34:23 UTC 2014     root@amd64-builder.daemonology.net:/usr/obj/usr/src/sys/GENERIC  i386

I have a problem with pkgng and freebsd-update because they are now very slow.
For example pkg update takes more than one minute to proceed, although the download speed of individual files is correct (fiber connection) :

pkg-1.2.7_4.txz                     100% 2001KB   2.0MB/s   2.0MB/s   00:01

This is the same for freebsd-update : slow request but fast download. It looks like a kind of very high latency.

top, iostat and uptime are ok, CPU / RAM / HDD solicitation are very low. For example here is my load average :

# uptime
 1:35PM  up 15:16, 1 user, load averages: 0.29, 0.30, 0.25

I'm running 5 jails, they are ok. pkgng and apt-get (kfreebsd) are very fast.

I have not used freebsd-update and pkg for a while and I added an IPv6 gateway + 6to4 client tunnel role and kfreebsd jails. It may be the cause.

Anyway I don't really understand why my host is slow and my jails fast... can you help me ?

Regards

Yes, that could be it. If IPv6 isn't configured properly you will get a delay when the system first tries to connect with IPv6 and then falling back to IPv4. Another issue may be with name resolving. That could cause an initial delay too.

Thank you, you may be right, it looks like an IPv6 issue. ping6 google.com does not work. I will check my tunnel or disable IPv6.
