Subject[BENCHMARK] Lmbench results for 2.5.54
DateFri, 3 Jan 2003 12:09:32 +0530
From"Aniruddha M Marathe" <>
Hi,
Here is a comparison of results of 2.5.52 and 2.5.53. The figures in the table below indicate median of 5 repetitions of tests. This result doesn't have many 
Differences than the previous one.


						2.5.54	2.5.53
==============================================================================
Processor, Processes - times in microseconds - smaller is better
1. Null call				0.44		0.46
2. stat					29		27
3. exec proc				1600		1528
------------------------------------------------------------------------------
Context switching - times in microseconds - smaller is better
1. 2p/0K ctxsw				1.560		1.430
------------------------------------------------------------------------------
*Local* Communication latencies in microseconds - smaller is better
1.AF UNIX					19		21
2.UDP						30		33
3.TCP						75		125 
4.RPC TCP					106		156
------------------------------------------------------------------------------
File & VM system latencies in microseconds - smaller is better
1. PIPE					554		386
2. AF UNIX					109		136
3.
