From 0cca4ba83c24df76a41f21ac5e350a6f6a1c89e7 Mon Sep 17 00:00:00 2001 From: Robert Watson Date: Mon, 25 Feb 2002 19:47:05 +0000 Subject: [PATCH] Add a lock contention measuring tool to the list of desirable features without an owner. To measure the effectiveness of our locking strategy, optimality of mutex pools, etc, we'll need a tool that tells us what locks are the "hottest", as well as other useful statistics such as average latency to wait on a lock, perhaps throughput on the lock, etc. This task will require some relatively in-depth analysis of what we need to know, not just hacking, but should prove interesting and highly valuable. --- en/smp/index.sgml | 11 ++++++++++- 1 file changed, 10 insertions(+), 1 deletion(-) diff --git a/en/smp/index.sgml b/en/smp/index.sgml index 31a571b436..c74779422f 100644 --- a/en/smp/index.sgml +++ b/en/smp/index.sgml @@ -1,6 +1,6 @@ - + %includes; @@ -885,6 +885,15 @@ &status.new; + + Lock contention measurement tool to measure heat of various + locks, including Giant, and permit more directed performance and + locking strategy optimization. +   + 25 February 2002 + &status.new; + +
