OK.

 

Very new to all this. Learning how it all works.

 

Win 10 vm transfers about 115+MBps to and from NAS or any other device on the network.

 

OS X el Capitan vm transfers about 30-40MBps to and from NAS or any other device on the network.

 

Both use same br0 to access network.

 

Thoughts about why? Is this normal with OS x in a vm?

Does OSX detect the virtual ethernet as 1GBit?

Yes, it shows gigabit in network utility. I even tried changing network>hardware from auto to 1000baseT to ensure that wasn't a problem, but no difference in speed.

 

Displayed transfer speed in the vm increase slightly when sending files to and from the cache disk where the vm is stored but seem to fluctuate more wildly dipping as low as 4-6MBps.

 

---update

I was reading that at times you can't trust the listed speeds in the vm, so watching them via unRaid shows huge swings when writing to cache or NAS.

 

I've attached screenshots from a 3.75GB files transfers.

 

When going from NAS to OS X vm, it appears to receive data (not at full gigabit speed) then pause receiving and write to the cache disk.

 

When transferring data from the vm to cache and back, the same write cycle appears.

 

The ssd I'm using is connected to the DL380's dvd sata port since unraid doesn't recognize the p4xxx raid card in the machine (i'm waiting to get a new controller soon.)

 

Maybe just a bad install?

 

I'll do some win 10 transfers with the same file and post them up in a while for comparison.

So now the win 10 vm is acting up.

 

It cycles writes to the virtual disk just like  the OS X vm, but not when sending to the Nas.

 

So am I hitting some sort of network or write buffer on the machine or unRaid software? The ssd is maybe 2 months old and seems to be fine so I'm not sure that is the issue.

 

CPU usage never hits above 20% except for the random peak. I have 24GB of ram, each machine has 8-10GB but aren't on at the same time leaving 14-18 free/cached.
