autocorking_size - INTEGER
|
|
|
|
|
Setting SMC auto corking size:
|
|
|
|
|
SMC auto corking is like TCP auto corking from the application's
|
|
|
|
|
perspective of view. When applications do consecutive small
|
|
|
|
|
write()/sendmsg() system calls, we try to coalesce these small writes
|
|
|
|
|
as much as possible, to lower total amount of CDC and RDMA Write been
|
|
|
|
|
sent.
|
|
|
|
|
autocorking_size limits the maximum corked bytes that can be sent to
|
|
|
|
|
the under device in 1 single sending. If set to 0, the SMC auto corking
|
|
|
|
|
is disabled.
|
|
|
|
|
Applications can still use TCP_CORK for optimal behavior when they
|
|
|
|
|
know how/when to uncork their sockets.
