tcp_recv_hiwater_def

tcp_recv_hiwater_def is currently set on our system at 32768.

We want to test using a buffer size of 65536.

But we don't want to apply it globally. Can we apply this setting to a specific NIC?
The Devil is in the detail.

Hi Kevin,

This tunable adjusts the system-wide behavior of the TCP transport so it would affect any interface using the TCP transport. I don't know of a way to limit the exposure to a specific interface.

Regards,

Dave

Re: tcp_recv_hiwater_def

There is no way to set TCP parms on a per-interface basis. However, you can of course set them on a per-connection basis with setsockopt, so that would be the way to test.
