twa, 3ware performance issue

Hey everybody, I just threw freebsd 7.1 on my server to replace Debian, and I have hit a snag...
The system is a dual quad core, currently only with 4GB of ram, and a 3ware 9650se-12 raid card with 7 750GB drives hooked to it in raid-6. With linux I could easily get around 100+MB/sec writing, but right now I'm only capable of getting around 2-3Mb/sec with freebsd. The array is partitioned with GPT with one partition using the whole 3.4TB and then i just ran newfs on the single partition.

I ran Bonnie++ and here are the results:

Right now it's running 7.1-Release and I just realized there are some patches i need to apply, but I doubt that's going to fix my problem

Here's the tw_cli output

Correction from the speeds posted above, I meant to say 50MB+ instead 100MB+ for writing

- I ran `dd bs=1024 if=/dev/zero of=/file/on/disks count=1M` and the best speed I could get was 3MB/sec
- I just upgraded to 7.2-RELEASE and the problem is still the same.
- Something I changed between the reformat, was that i installed a new nic, http://www.newegg.com/Product/Product.aspx?Item=N82E16833106123, which seems to be working fine...
- I have tried hw.pci.msi_enable=0 & hw.pci.msix_enable=0 & vfs.read_max=256 & vfs.hirunningspace=5MB but the results were the same...
- Also here is the dmesg output that I should have put in the first post. Also, 192.168.1.26 is the desktop that I am using to ssh into the server. I'm not really sure why there is the arp message at the bottom.
(in next message because it was too long..)

Do you have write caching enabled on the array? You can see this from the 3dm2 web management interface or from the tw_cli(8) utility.

For example:

I just enabled write cache the write cache and I'm now seeing write speeds over 150MB (when doing dd if=/dev/zero bs=1024 count=2M..) The thing is I do not have a BBU, just ordered it, so I had disabled this feature when debian was on the server and I never noticed any speed difference.
So I overlooked this setting as I was trying to figure out what was going on. The weird thing is that my write performance was fine on linux without cache, so I'm not sure what's up with that.

Thanks for the help though

Strange behavior. I using some 9550er 3ware Controllers and never noticed such problems. Did you contacted the 3ware Support too for this problem?

No, I never contacted 3ware because I never really felt that there was an issue with the card, because it worked fine while using linux I figured there must be some configuration error on my part. Had I not been able to figure it out then I probably would have contacted them, but luckily I didn't have to go that far...

What I still think is strange is that with cache off while running Debian, the performance was still fairly good, but in FreeBSD, with the cache off, the performance was terrible...

Now i got the same behaviour on a 7.2 release amd64 with a new 3ware 9550SXU-08LP / PCI-X / Single.

Without the write cache enabled the disk performance is really low. This do not depend on the raid level. Even if i use the disks as JBOD the perfomance is to low.

We using 3ware Controller for years on FreeBSD, i never recognized such a behaviour in the past.

Ill try to contact 3ware.

Any other FreeBSD Users can confirm that behaviour?
