Subject: [benchmark] Interbench 2.6.16-ck/mm
Date: Sat, 25 Mar 2006 13:51:56 +1100	[thread overview]
Message-ID: <200603251351.57341.kernel@kolivas.org> (raw)

Here are interbench numbers for a pentium4 HT with 2.6.16-ck1 and 2.6.16-mm1

The rules I use for flagging diffferences are:
1. Deadlines met is the primary endpoint.
2. When latency is out of bounds, what is the worst max latency as that will 
be the most noticeable jerkiness, stutter etc, but I only flag them if at 
least one value is >=7ms since that is required to be human perceptible.

Summary:
	Deadlines	Max Latencies
	ck	mm	ck	mm
Audio 	1	1	1	1
Video	5	0	5	1
X	4	2	6	1
Game	2	4	5	3

Note that most of the differences between -ck and -mm on this benchmark are 
due to the staircase cpu scheduler in -ck. It has staircase v14.2 as recently 
posted to the mailing list.

Cheers,
Con
