[SOLVED] Not to sure whats going on?!? Slow Writing speed

[Redxd]

So i'm a tad confused as to what is causing my issue

Pretty much like a few people complaining on here I am only getting write speeds of max 24MB/s to my server (transferring Blueray rips)

Hold on, that's the max speed you will get writing to parity I see some of you yelling at me hearing this complaint over and over again. Yes that's true, but not when you have a cache drive setup.

 

I have my HP Microserver N36L set to 1000Full

A brand new D-Link 8GB switch (DGS-1008D) inbetween

And Windows 7 box set to 1000Full

 

Have replaced both sets of cables going to the new switch with 1xCat5e and 1xCat6 patch cables (borrowing permanently from work

 

Like I said before have Cache setup and also Cache dirs turned on as well. After copying said files to the server it even tells me there is pending cache.

 

So i'm a bit confused as to where I have gone wrong (If I even have) and how I can fix it.

I have also attached the syslog as well.

Is the share set to use the cache?

[Redxd]

All 3 of my shares are set-up to use Cache. And like I said before the cache is working like it should be moving stuff at 3am (Or what ever the time has been set I forget)

Your system is too slow for unraid to work properly. Get a faster cpu. Even though unraid claims it can run on spare hardware you have lying around or hardware that is obsolete, that does not mean it will work at its best. If you want any performance by todays standards, get modern, faster hardware.

Jowi you are wrong. My system runs perfectly fine with the hardware I am running. Just because the CPU isnt such a high number doesn't mean its affecting what issue I am having.

 

 

The issue ended up being with a bios setting. You need to modify the bios, as my cache drive was running off the sata port on the motherboard it was limited as to what it could ran at.

As mentioned in the post below. Although myn didnt say 'SATA IDE combined mode' it said something along the lines of 'SATA ports 5/6 IDE' Enabled.

I assumed your basic settings were right to begin with.

 

So what speeds do you have now? On a fast machine you should get about 100MB/s copying over the network to your cache disk... writing to a parity protected user share should be at about 40 to 50 MB/s...

FYI I had a Celeron 430 on a X7SBE MB and got close to these speeds.  I've since moved on to VMs on ESXi for unRAID.  The biggest difference I saw when I went with a faster processor was the GUI responsiveness.  I went from the 1.8Ghz single core Celeron to a 3.2Ghz single core VM.  It got faster in unMENU and the unRAID GUI.  The access speeds were 75-90MB/s to cache and 35-45MB/s to protected array on my Celeron 430 based unRAID install.  I didn't have many plugings no SAB/Transmission ect...  Just a few for server health and status displays.
