Enlightenment CVS committal
Author : onefang
Project : e17
Module : libs/ecore
Dir : e17/libs/ecore/examples
Modified Files:
exe_example.c
Log Message:
* More accurate throughput tests by removing most of the overhead.
* Don't fill the timing tests with stdio shit, gives much better results.
Now the only overhead is a tiny fraction of the tested time.
140MB/s in both directions in line buffered mode on my lightly loaded Athlon
3000.
