socket = l:TCP_NODELAY=1
socket = r:TCP_NODELAY=1
here are some resources I have used to try and resolve the issue
from the manual these sockets are described in an example
socket = a|l|r:option=value[:value]
Set an option on accept/local/remote socket
The values for linger option are l_onof:l_linger. The values for time are tv_sec:tv_usec.
Examples:
socket = l:SO_LINGER=1:60
set one minute timeout for closing local socket
socket = r:TCP_NODELAY=1
turn off the Nagle algorithm for remote sockets
socket = r:SO_OOBINLINE=1
place out-of-band data directly into the
receive data stream for remote sockets
socket = a:SO_REUSEADDR=0
disable address reuse (enabled by default)
socket = a:SO_BINDTODEVICE=lo
only accept connections on loopback interface
