[BENCHMARK] LM bench results summary for 52-mm1 patch

[Aniruddha M Marathe]

Hi,
Here is a brief summary of results of LM bench on kernel 2.5.52

								2.5.52-mm1	 	2.5.51
==============================================================================
Processor, Processes - times in microseconds - smaller is better

1. Null call						0.44			0.46
2. open close			 			30			28
3. single handle						5.13			5.22
4. fork proc						400			363
5. sh proc							8279			7967
------------------------------------------------------------------------------
*Local* Communication latencies in microseconds - smaller is better
1. TCP connection						174		161
------------------------------------------------------------------------------
File & VM system latencies in microseconds - smaller is better
1. 0K file delete						60		57
2. mmap latency						615		640
------------------------------------------------------------------------------
==============================================================================

Rest of the results are not much different.
