Transfer Speeds

[ethereal]

you can see my current equipment in my signature - i recently upgraded my equipment. i use zfs, raid-z2 and cifs. my hdd are consumer.

i never really got fast transfer speeds about 44 MB/s for a single file and 54MB/s for 2 files at a time - with my faster cpu i thought i may get faster transfers but they have stayed the same.

i think i am being limited by cifs being single thread - my old cpu and my new cpu are both dual core is this why the transfers are almost the same, even when my new cpu is faster?

am i correct in thinking that quad-core would give me faster tranfers if i transfer 3 or 4 files at once?

I can't see your hardware as I'm on my phone.. Typically the answer is add more ram and ensure your not on realtek NICs..

FreeNAS-9.2.1.5-RELEASE-x64

My FreeNAS components - Supermicro MBD-X9SCL-F-O| Intel Pentium G2130 3.20GHz (Dual Core) | 32GB Crucial PC3-12800 1600 MHz DDR3 SDRAM (ECC) | 3 x 3TB Seagate and 3 x 3TB Western Digital HDD in RAIDZ2.

32GB is the max ram and i have intel nic's

thank you

Hmm.. I have a very similar setup.. What are your network components? I'd start there.. I can saturate no problem.. What are you transferring and what are the specs of your client PCs?

Only other thing I can think of is dual types of HDD but shouldn't be an issue..

all the hard drives are consumer - 4 are 7200 rpm there are 2 AV-GP drives (5400 - 7200 rpm)

i use the freenas as a media storage - i have a HTPC and a laptop using XBMC for watching videos and films stored on the freenas and the main pc dowloads and transfers files to the server. the main pc also watches videos and films. i have a max of 3 computers at a time using the freenas server. all are windows 7 pcs

100 Mb/s = 12.5 MB/s...so you're actually quite lucky to be getting 44 MB/s and 54 MB/s (caching?). Wireless will most likely be even slower. Looks like your bottleneck is the network, not the server.

sorry - i mean't ESR600H

Gigabit WAN Port - Up to 300 Mbps wireless speed in both the 2.4 and 5 GHz frequency bands

4 Gigabit LAN Ports

Can you run iperf with the FreeNAS box as the client and each of your Windows PC as server (one at a time) to verify what your network throughput is? Just to eliminate your network as the problem

Ah. Still, if you're transferring anything over wireless, you will probably get about 80 Mb/s real speed = 10 MB/s. Only 3-stream N450 can break 100 Mb/s, and only at short range.

 

[ethereal]

main pc - 465Mb/sec

laptop - 68.7Mb/sec

htpc - 770Mb/sec

Well, the 465 Mb/sec is definitely not good for a gigabit connection. I would say something is wrong there. The laptop speed seems normal for your WiFi and I would expect slow CIFS speeds there. The HTPC seems a bit low as well. Maybe you need to try moving cables around and checking again. Also, make sure you don't have a bunch of traffic running from something else.

I was getting speeds like that with a PCI gigabit NIC. With a PCIe gigabit NIC, speeds were ~930 Mb/s. I would guess it's how the gigabit NIC is connected to the motherboard, whether through an add-in PCI/PCIe card or by the motherboard manufacturer.

ah, I see, didn't think of that as the potential bottleneck. Would be interesting to know what he has for his NIC then.

my nics are gigabit - on the mb

Does your motherboard manual state which controller is used? Google that part number and see if it's a PCI or PCIe part.

My onboard chipset in my main PC is one of the more popular ones: a Realtek 8111. They're popular because they're cheap. That said, I do get nearly full gigabit speeds from it using iperf. However I wouldn't trust it for sustained high speed file transfers or general overall reliability, so I'm using this:

Peace of mind for not much money.

Still, even if it's a low-end chipset integrated into the motherboard, it should be faster provided it's attached using PCIe.

my main pc - The RTL8111E supports the PCI Express 1.1 bus interface

htpc - Realtek GbE LAN chip - can't find any information on the chipset version
