Subject[BENCHMARK] LM bench results summary for 52-mm1 patch
Date
From
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.
