New Revision: 26391
Modified:
trunk/freenet/test/freenet/client/CodeTest.java
Log:
Add a benchmark to the junit test; launch it with -Dbenchmark=true
At the moment it produces weird results:
[junit] Getting ready for benchmarking
[junit] Native8Code[k=192,n=256]
[junit] PureCode[k=192,n=256]
[junit] Native code took 239ms whereas java's code took 76ms.
