Slow unraid when accessing and transfering files

Hello.

 

It's a unRAID Server Plus version: 4.7 I installed on my friend who works in photography.

 

The setup is an old Asus P4p800 with pentium 4 3Ghz and 1 Gb ram.

It has 6 Hdd's all Wd green 2Tb each

parity drive is connected to onboard sata port

Data drives: one on onboard sata, others in pci sata card Sil3114

 

He complains about slow access when browsing the folders in the unraid, takes a lot of time to open them in adobe bridge cs5

Also copying photos from flash card to server sometimes is really slow, like 1MB/s.

 

I'm thinking about doing an upgrade to corei3, but I'm afraid that it will not improve performance as expected.

 

Syslog is attached

 

PS:They have also 2 other regular NAS  machines  using raid6 that work with no problems.

I don't think that's because of drives have to spin up because it hapens when he is entering and exploring folders and continues slow if he browses to another folder.

Could it be because he has a lot of files/folders?

He has like a folder for each year, and inside one for each month, inside this for each work that have inside about 1000 or more photos in raw and jpeg, about 10/20 MB each file.

 

I monitored the RAM. free ram is only about 20MB maybe this is the problem? It has 1Gb installed...

Linux will allways eat all your RAM, free mem does not mean a lot with unraid...

 

If you think it is a folders issue, are you using cache_folders ?  This will make sure the folder structure is provided from memory and not from disk.. Actually meant to avoid disks spinning up when folder browsing..

 

Also check if turning on "spin up groups" helps, it might (but is default on)

I'm a litle afraid about using a beta version on a running server with valuable data..

 

Today some new issues appear while copying files from a compact flash card to the server. after a while windows says it cannot access network share. if I try again later it continues copying.  If I check the properties of the target folder it has the read only attribute semi-checked, I clear it out and then try again the Windows 7 - Error 0x8007003B: An unexpected network error occurred, show's up but then It I click try again and it continues copying fine again.

Speed is  about 6-9MB/s. if I copy to local drive I get around 20MB/s reading from the Flash card.

So this is how slow the Unraid is.

are you using the onboard network card? or an addon card?

 

i noticed these lines

 

Jul 12 18:21:53 Unraid kernel: e100: Intel® PRO/100 Network Driver, 3.5.24-k2-NAPI

Jul 12 18:21:53 Unraid kernel: e100: Copyright© 1999-2006 Intel Corporation

Jul 12 18:21:53 Unraid kernel: Broadcom NetXtreme II CNIC Driver cnic v2.0.1 (Oct 01, 2009)

 

the Intel Pro/100 is only a 10/100 network card.

 

I would also check that all cards, cables and switches are gigabit compatible. If your network is only running at 100Mbps you will not get any higher than 10Mb/sec

 

How fast is it to copy a large file off the server onto the computer?

I'm using onboard gigabit marvel 88E8001  chip.

Jul 12 18:21:53 Unraid kernel: skge 0000:02:05.0: PCI INT A -> GSI 22 (level, low) -> IRQ 22

Jul 12 18:21:53 Unraid kernel: skge 1.13 addr 0xfbffc000 irq 22 chip Yukon rev 1

Jul 12 18:21:53 Unraid kernel: skge eth0: addr 00:0e:a6:20:a8:21

 

don't know why those e100 lines appear.

 

I get around 30MB/s reading and 10MB/s writing a 1Gb file

Hi

the hdparm command can't do right now, takes a long time to show anything must be because I'm copying 30gb of photos from a laptop to the server and the rate is 7MB/s.

also is this normal?

that might be true, because that laptop only has a 100mbit lan, but copying to other servers/computers from this lapotop the rate is 11MB/s...

 

here is the hdparm:

root@Unraid:~# hdparm -tT /dev/[hs]d?

/dev/sda:
Timing cached reads:   1768 MB in  2.00 seconds = 883.85 MB/sec
Timing buffered disk reads:  262 MB in  3.02 seconds =  86.72 MB/sec

/dev/sdb:
Timing cached reads:   1776 MB in  2.00 seconds = 888.07 MB/sec
Timing buffered disk reads:  258 MB in  3.00 seconds =  85.99 MB/sec

/dev/sdc:
Timing cached reads:   1784 MB in  2.00 seconds = 892.18 MB/sec
Timing buffered disk reads:  254 MB in  3.01 seconds =  84.47 MB/sec

/dev/sdd:
Timing cached reads:   1796 MB in  2.00 seconds = 897.79 MB/sec
Timing buffered disk reads:  264 MB in  3.00 seconds =  87.98 MB/sec

/dev/sde:
Timing cached reads:   1762 MB in  2.00 seconds = 880.80 MB/sec
Timing buffered disk reads:  324 MB in  3.01 seconds = 107.63 MB/sec

/dev/sdf:
Timing cached reads:   1672 MB in  2.00 seconds = 836.09 MB/sec
Timing buffered disk reads:  344 MB in  3.02 seconds = 114.06 MB/sec

/dev/sdg:

I don't think the CPU power is the issue, I think it's the shared PCI bus. Since that motherboard has no way to use a faster disk interface, a motherboard upgrade would seem to be the only solution. If you could get away with 3 or 4 total drives, the old motherboard would probably run ok.
