Good afternoon! My config: ESXi 6.7.0 19195723, VM CHR 7.5, VM Win10 Pro 21H2. VM CHR and VM Win10 connected to one vSwitch. The problem is the low speed of the UDP in one direction:
Bandwitch Test on CHR ---> Bandwitch Test v0.1 on Win10
TCP - Tx/Rx Current: 863.8 Mbps/3.5 Gbps (CPU 90-99%)
UDP - Tx/Rx Current: 11.7 kbps/261.9 Mbps (CPU 7-11%)
I tried different network adapters on the VM, installed Win7 for the test, changed the settings of the network card in Win10 (such as LRO, buffer ...), but it does not help.
Thanks for any advice and help!
