Hello,
I am direct connecting windows server 2012 R2 Essentials with a Windows 10 PC. I'm having trouble with transfer speeds. I'm finding my cap at about 200MB/s speeds (2.0 roughly gigabits). enabling jumbo frames and all other options that Linus and the cinevate blog covers, I'm only getting 300MB/s speeds (2.8 roughly gigabits). I'm getting pour performance and I've spent 2 days trying to discover the issue. If anyone has any input, I would truly appreciate it.
I'm utilizing 2 intel x540T1 NIC. To give you an idea of my network configuration. My Server NIC is 192.168.2.1 and my Windows 10 PC is 192.168.2.2. My 1GbE network is on the default gateway 192.168.1.1. I'm pretty sure I have this portion of it configured correctly, as I can transfer files back and forth between RAM drives, and I'm able to get a reading with ntttcp. ntttcp gave me a throughput of 1128MB/s and when I turned on Jumbo frames it gave me a reading of 1048MB/s. So the speed is there, I'm just wondering what the bottleneck is, or if I need to do some more configuration.
Thanks in advance.
Windows Server 2012 R2 Essentials:
AMD Phenom x4 955
Asus M5a99FX Pro R2.0
32GB RAM
Intel x540T1 in the main PCI-Express 16x slot (Blue)(removed the video card and remote access)
LSI MegaRAID 9266-8i in the second PCI-Express 16x Slot (Blue)
Configured 20GB of RAM into a RAM Drive to test transfers
Note: I get 80% CPU utilization when I get 300MB/s Transfers
Windows 10 PC
Intel i7 3930 six core
Sabertooth x79 motherboard
32GB RAM
GTX 580 in first PCI Express 16x slot
Intel x540T1 in the second PCI-Express 16x slot
Configured 20GB of RAM into a RAM Drive to test transfers
NOTE: I get 4% CPU utilization when I get 300MB/s Transfers
If anyone can detect my bottleneck, or have an info on configuration, I'm all ears as I have tried and tried with this set up. I'm hoping to utilize my server as a mass storage to work off of for video content. I would really like to saturate the RAID that I have in mind for the future, but first i need to prove that I can get atleast 750 MB/s or even 1GB/s speeds.
