ZFS Slow

S

Sebastian

Hello ,

I have a brand new FreeBSD 10.3 installation. My host system running on a 32 GB SSD and I have another 3x4 TB Pool which I have imported (old FreeNAS pool). The problem is that my read and write are horrible slow. I used bonnie and to benchmark the disks. My SSD got 5 MByte/s write. On the FreeNAS Pool I got 8 MByte/s read on each disk. Results in round about 20-25MByte/s.
(RAIDZ1)

Because I have full disc encryption on I think maybe I'm missing a kernel module? CPU is 80% in idle while doing the test.

Code: 
freebsd% kldstat
Id Refs Address            Size     Name
1   28 0xffffffff80200000 17bc680  kernel

Sure. The system should handle zfs without problems. Used FreeNAS with the same hardware and it runs well, but ton of bugs...

I'm having the same issue, the system is really slow, but it was not happening on 11-CURRENT and only happened after I moved to RELEASE (fresh install).

My system specs are:
Intel core i5 3330 3.0GHz
6GB RAM
1TB Hitachi HDD
 
The motherboard had a really old bios. I updated it to the latest version and all performance problems are gone. Could't find any specific entry in the changelogs which can cause such a problem.

Now I can easily saturate my gigabit ethernet.
