From fb1322e40854dbbc4fcdd3cd783e7b83a5010b96 Mon Sep 17 00:00:00 2001 From: David Greenman Date: Mon, 23 Jan 1995 19:21:49 +0000 Subject: [PATCH] Decrease MCLBYTES from 4k back to 2k. It isn't likely that we'll be doing page flipping anytime soon and 4k just wastes memory. Performance via the looback interface will decrease slightly by this change. Idealy, we need buffers that can have variable sizes, but this requires a rewrite of far too much code at the moment. --- sys/i386/include/param.h | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/sys/i386/include/param.h b/sys/i386/include/param.h index fdc550b3fbd..a127d5f58a6 100644 --- a/sys/i386/include/param.h +++ b/sys/i386/include/param.h @@ -34,7 +34,7 @@ * SUCH DAMAGE. * * from: @(#)param.h 5.8 (Berkeley) 6/28/91 - * $Id: param.h,v 1.15 1994/05/25 08:56:14 rgrimes Exp $ + * $Id: param.h,v 1.16 1994/09/18 22:05:22 bde Exp $ */ #ifndef _MACHINE_PARAM_H_ @@ -103,7 +103,7 @@ #endif /* MSIZE */ #ifndef MCLSHIFT -#define MCLSHIFT 12 /* convert bytes to m_buf clusters */ +#define MCLSHIFT 11 /* convert bytes to m_buf clusters */ #endif /* MCLSHIFT */ #define MCLBYTES (1 << MCLSHIFT) /* size of an m_buf cluster */ #define MCLOFSET (MCLBYTES - 1) /* offset within an m_buf cluster */
