Consider increasing OS socket buffer (SO_SNDBUF
, SO_RCVBUF
)
#1962
Comments
Are we currently running with the OS defaults? What do other stacks use? |
In Firefox we attempt to set it to 1 MiB. I wasn't aware of this until today trying to add another pref. # Receive buffer size of QUIC socket
- name: network.http.http3.recvBufferSize
type: RelaxedAtomicInt32
value: 1048576
mirror: always |
Thanks for finding this out. We could do the same in neqo, but would it be worth it? Do we also do something for the send buffer? |
As far as I can tell we only alter the receive buffer, not the send buffer. I am not familiar enough with the code base to know for sure.
👍 worth experimenting with in |
For increased performance, we might want to increase the OS UDP socket send and receive buffer.
