I've been running into an issue that I need some advice on.
1st: I have two desktop PCs, both installed with 10GB NICs and 1GB nic (for remote access).
- PC1: OptiPlex 9010 / Win10 Pro / 16GB mem / i7-3770 @ 3.4GHz quad core (acting as client)
- PC2: OptiPlex 990 / Win10 Ent/ 12GB mem/ i7-2600 @ 3.4GHz quad core (acting as server)
I've connected each of these PCs, on their 10GB Nics, to a Cisco C9300-24T switch. On the switch I've installed two SFP-10G-SR-S and ran LC to LC OM3 (multimode) fiber to the devices.
Now, the test that I'm performing is between these 2 devices running ONLY at layer 2. When I run a default TCP Test, I'm only getting 2.47 GBytes transfer and 2.13 Gbits/sec bandwidth. When running a UDP test, while setting the bandwidth to unlimited "-b 0", i get 3.18 GBytes transfer and 2.73 Gbits/sec bandwidth.
When I directly connect the 2 PCs together and running the same tests, I get even worse results.
Why am I not see better transfer and bandwidth speeds?
