Is this speed normal with HP microserver?

[neiklot]

Hi guys. I'm starting with FreeNAS but I really like it!

The thing is that I realize that I can't get max gigabit speed. When I run iperf between a windows machine and my HP microserver running FreeNAS I get about 650Mbps. I changed cable, I checked that dedup and compression were already off.

If I run dd

dd if=/dev/zero of=/mnt/my_volume/temp bs=2048k count=10000
10000+0 records in
10000+0 records out
20971520000 bytes transferred in 11.934280 secs (1757250554 bytes/sec)

I get a real good speed!

But.. why am I just reaching 650Mbps over lan?

Thanks guys for your help!! :)

PD: I have 4gigs of RAM and a 2 sata 2TB HDDs with zfs mirror 0

Post your entire system specs. Right off the bat, 8GB RAM is the minimum required to run FreeNAS 9.
If you're only seeing 650Mbps running iperf, you can forget all the storage stuff, because iperf isn't relying on the storage. It's only testing the network. What NIC do you have in the Microserver and on the client system? Realteks by chance? A cheap/crappy NIC on either end will give you poor performance.

NAS Specs:
HP Proliant Microserver gen8
Intel® Celeron®G1610T (2 cores, 2,3 GHz, 2 MB, 35 W)
4gb ram ddr3 1333
2x2TB seagate HDD
Ethernet 332i NIC

Client Specs:
Intel Core i5-4430
Gigabyte H97-HD3 motherboard
8gb ram ddr3 1600
Ethernet Realtek PCIe GBE Family Controller


I think both are good NICs and that they should run fine..

Give it some more RAM and see if that improves things. If it doesn't, post an update and you might get a little more help :D

Yes, I have an extra 4gb ram ordered. It should arrive about friday or so.. I will keep you informed! :)

Realtek. Throw a proper NIC in the client system, or find a client system that uses an Intel NIC, and try it again.
