Subject: nonagle flags for TSQ
Date: Fri, 07 Feb 2014 16:08:39 +0100 [thread overview]
Message-ID: <87fvnv2c5k.fsf@linutronix.de> (raw)
Hi,
This email is referring to your Linux patch
46d3ceabd8d98ed0ad10f20c595ca784e34786c5.
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=46d3ceabd8d98ed0ad10f20c595ca784e34786c5
I have a question about the use of tcp_write_xmit() in
net/ipv4/tcp_output.c
When tcp_write_xmit() is called, the nonagle flag of the tcp socket is
ignored and instead 0 is passed. This causes the Nagle-algorithm to be
used even if it should not be, which in some cases causes a large delay.
Was there a reason that 0 was hard-coded?
Although current mainline code has been refactored, 0 is still
hard-coded for TSQ cases.
