I'm having a problem that I can't track down.  When up loading my files it starts off at about 70MB/s goes for a while and then stops.  Waits for a bit at 0 then starts again at full speed.  Keeps doing this the entire time. 

 

I've tried with and without cache drive.

Copying from different drives to unRaid

Directly connected my computer to unRaid with two different know good cables

One cat5e and one cat6

Enabling and Disabling Jumbo Frames / Setting MTU to 9000

Adjusting rx buffer to 4096

Rebooting everything

 

The only thing that I can find odd is there are some dropped packets but it doesn't look too high.  (<.002% if I did my math right)

 

Running the most current stable version 6.1.9.  Haven't looked into 6.2.

 

Any ideas?

 

Thanks,

Rich

Had the same issue with reiserfs, convert to xfs, start with your cache to confirm.

Wow.  That's a fast response.  I emptied my cache and formatted it as XFS.  It looks likes it's working much better now.  It looks like I've lost about half of my transfer speed, (60MB/s to 30MB/s) but I'm guessing that's because of buffers filling up.  I'm going to play with a bit to make sure it's really gone and then mark this solved.  I'll also have to find time to change over the rest of the array.

 

Thanks,

In the end transfer speed should be the similar, but with XFS it's constant instead of the seesaw effect with Reiser, but there was at least one user that reported better speeds after converting to XFS.

Converting to XFS was the fix. 

Took a while to convert the entire array but no more problems.  The speed didn't really drop any I was just watching it more.  The first gig or so always transfers at about 60-70MB/s then drops to a steady 30 or so.  I'm guessing it's buffering into ram but when that fills the speed drops.  Put a small SSD in and speeds increased so it's a slow drive.  Thanks for all the help.
