Subject: [PATCH][RFC 3] cleaning up struct sock
Date: Thu, 20 Dec 2001 01:23:39 -0200	[thread overview]
Message-ID: <20011220012339.A919@conectiva.com.br> (raw)
In-Reply-To: <20011218033552.B910@conectiva.com.br> <20011217.225134.91313099.davem@redhat.com> <20011218185200.A1211@conectiva.com.br> <20011218.130809.22018359.davem@redhat.com> <20011218232222.A1963@conectiva.com.br>

Ok, patch for 2.5.1, without the bogus cvs $id strings hunks, being used
in this machine now.

Available at:

http://www.kernel.org/pub/linux/kernel/people/acme/v2.5/2.5.1/
sock.cleanup-2.5.1.patch.bz2

Ah, the lat_unix_connect results on a pentium 300 mmx notebook:

2.5.1 + this patch
UNIX connection cost : 96.1749 microseconds
UNIX connection cost : 96.3361 microseconds
UNIX connection cost : 97.2310 microseconds
UNIX connection cost : 101.9180 microseconds
UNIX connection cost : 97.2461 microseconds

2.4.16 pristine
UNIX connection cost : 112.7034 microseconds
UNIX connection cost : 114.5494 microseconds
UNIX connection cost : 114.0923 microseconds
UNIX connection cost : 111.0959 microseconds
UNIX connection cost : 120.8419 microseconds

And about 100 KB of kernel memory saved for AF_UNIX sockets on a basic KDE
session (i.e., the AF_UNIX struct sock now is about 400 bytes when it is about
1200 bytes on a pristine kernel).
