Hi,
Here is a comparison of results of 2.5.55 and 2.5.54. The figures in the table below indicate median of 5 repetitions of tests. This result doesn't have many
Differences than the previous one.
2.5.55 2.5.54
==============================================================================
Processor, Processes - times in microseconds - smaller is better
1. Null call 0.41 0.44
2. Null I/O 0.58 0.82
3. stat 25 29
4. open close 26 30
5. sh proc 7117 7872
6. exec proc 1285 1528
------------------------------------------------------------------------------
Context switching - times in microseconds - smaller is better
1. 2p/0K ctxsw 1.100 1.560
------------------------------------------------------------------------------
*Local* Communication latencies in microseconds - smaller is better
1. PIPE 5.626 8.426
2. AF UNIX 13 19
3. UDP 24 30
4. TCP connection 126 146
------------------------------------------------------------------------------
File & VM system latencies in microseconds - smaller is better
1. MMAP latency 472 599
------------------------------------------------------------------------------
*Local* Communication bandwidth in MB/s - bigger is better
1. PIPE 554 634
