We are receiving higher than expected response time or timeouts when testing with NV, even when the emulation is with 0ms latency and without bandwidth restriction or packet loss. We are using Performance Center 12.53

The cause of this issue is due to certain network settings of some network adapters which affect the network emulation.

To fix this issue:

LR/PC 12.50 / 12.53- On each Load Generator / NV Test Manager:

1. Open Windows Control Panel.
2. Select Network and Sharing and then Change adapter settings.
3. Open the properties of the adapter/s through which the
application under test communicates
> select Configure > Advanced:

* Large Send Offload (IPv4) > Disable.

* Recv Segment Coalescing (IPv4), if the option exists > Disable.

LR/PC 12.53 Patch 4 / 12.55- On each Load Generator / NV Test Manager

1. Open Windows Control Panel.
2. Select Network and Sharing and then Change adapter settings.
3. Open the properties of the adapter/s through which the application under test communicates > select Configure > Advanced:

* Recv Segment Coalescing (IPv4), if the option exists > Disable.
