Hi,
I've got an productive ESXi 5.5 (1331820) Hypervisor with two Windows Server 2012 R2 (1x DC & 1xRDS), there are currently working about 15 people on the RDS.
They use programs which run over the network and access some data on the network share from the DC.
Both VMs run with VMXNET3 driver and vmtools is seems to be on the latest version.
Problem:
Now i think the network traffic between these two vms is pretty slow, because the users claimed about a long waiting time when saving an normal document or when working with programs which access the network drives.
At the moment i've got an maximal throughput form about 820Mbit/s, which seemed to be the max. to get out with disabled offloading and enabled jumbo frames.
Before i disabled offloading and enabled jumbo frames, i've got an throuput from about 400Mbit/s.
I tested the setup on a small development server but with ESXi5.1 and i've reached an throughput from about 1.4Gbit/s, with lower Hardware specs.
What i've tested:
- Tested network traffic between the two servers with iperf.
- Disabled all Offloading functions.
- Enabled Jumbo Frames
- Disabled Firewall & Antivirus
Hardware:
Dell Poweredge R420
32GB RAM
Intel Xeon E5-2407 (2.20GHz)
Perc H720 Raid 5
Broadcom 5720 1Gbit/s
Has anyone encountered simliar issues? I really need help on this.
Thanks
