I've looked at the other threads and have tried a bunch of things suggested there that didn't work, so here goes...
We have a FreeNAS 9.3 setup that was working fine in our old office. We moved upstairs a few weeks ago, and the whole server room was reconfigured. All the hardware is the same, just a new location. In the old office, we would easily get 100MB/s throughput to the FreeNAS box over our gigabit network. A few weeks before the move, a drive failed. After the move, I swapped that drive and it took about 24 hours to resilver. During that time we were getting about 1MB/S throughput on the high end, but that made sense because it was in degraded mode. After resilvering, we're getting an inital burst of speed over 100MB/s, but it rapidly drops to 10MB/s, where it remains for the duration of the file transfer. That's 1/10 of what we had before the drive swap.
I realize this is not a high end setup, but it has worked fine for us for many months.
Hardware details:
Motherboard: Honestly, can't remember. Something cheap we used for years with OpenFiler before switching to FreeNAS last year. Is there a command line tool I can use to get this info? I'd rather not pull the server out of the rack.
Intel(R) Core(TM)2 Duo CPU E7500 @ 2.93GHz
2GB RAM
Areca ARC-1280/1280ML RAID in pass-thru mode (16x 2TB drives)
Motherboard has onboard Gigabit (1 port)
Intel Pro 82546GB dual-port Gigabit card
Cisco SG 300-28 Managed Gigabit switch
Here's what I've tried:
* All three gigabit ports on the FreeNAS box. (all report 1GB on their LEDs, and in ifconfig, and on the switch, regardless of cable or switch port)
* Different ports on the switch
* Turned auto-negotiate off on the switch (it's set to 1000M Full Duplex)
* different cables (all Cat5e or Cat6)
* rebooted FreeNAS system
* rebooted Cisco switch
I've also tried copying to the FreeNAS box from multiple machines, all with the same 10MB/s speed limit. All machines on the network are gigabit.
Again, the weird thing here is that it all seemed to happen after a drive failure and resilvering - we used to get very consistent transfer speeds over 100MB/second, so I'm not sure that it's necessarily the network at all. Could something else have caused performance to suddenly degrade? The current status of the pool is "HEALTHY" and all the drives appear to be functioning normally.
If there's additional information that might help to diagnose this, I'm here all day and can post it. Just let me know.
Thanks!
