Slow/hanging at random points

[hayer]

Hi,

yesterday I added 6x3tb drives to my FreeNAS. As of now the specs are;
Intel i3-3225
32GB ECC RAM
6x1 TB RAIDZ1
6x3 TB RAIDZ2
FreeNAS 9.2.1.3 x64

The problem is that when I SSH in it sometimes stop for about 10-15 seconds and I can't do anything. Then it goes on like nothing happend. This happens even while I'm just typing into the SSH. I've tried from multiple computers and different SSH clients. I've also tried connecting to the NAS directly, same result.

It seems to also affect the web-ui because sometimes it takes like 20sec to load a page, other times it takes like 1-2sec(the normal).

This started after I added the disks, what have I screwed up now?


Edit:
And sometimes the SSH times out when trying to connect..

Sounds like a DNS problem.

How is this a DNS problem? The ifconfig shows same settings as my other boxes and I don't see how the DNS has any effect on it timing out sometimes. If I try again right after I've gotten a timeout it succedes. If I clear my DNS cache, and the routers it still works on the first try - Just tested a couple of times.

Slow SSH is a classic symptom of DNS/hostname resolution issues. Slow loading of the UI is usually a networking (possibly DNS) issue.
