[PATCH] core/lwip: Avoid 3-second delay for a half-open connection
...ds). This can increase the time taken by
lpxelinux.0 to fetch its configuration file from a few milliseconds to
around 30 seconds.
Fix by immediately retransmitting the SYN whenever a half-open
connection is detected.

monitoring tcp writes
i''m using the following probe to calculate how many bytes are being written by tcp write calls, by process and total:
fbt:ip:tcp_output:entry
{
this->tcpout_size = msgdsize(args[1]);
@tcpout_size[execname] = sum(this->tcpout_size);
@tcpout_size["TOTAL_TCP_OUT"] = sum(this->tcpout_size);
}
I run this probe for N seconds.
I suppose that if i get the
